Don't Forget To Take...
I like to take a lot of thin white coat hangers as you never get enough in your stateroom. I just leave them on the ship when we leave. I like to take some battery-powered stick on lights for the inside of closets, the inside of your room safe, and the inside of the bathroom (the light switch is on the outside so you awaken your spouse when you turn on the light at night). Take a small flashlight or head light for emergencies and for looking under the bed. I take at least a dozen plastic clothes pins and a good string for a clothes line (you usually have a clothes line in the shower already). The thin white coat hangers are useful for drying clothes also. You can not take a clothes iron on a cruise ship; they X-ray the luggage and it will be confiscated. Irons are available in the launderette. Take some stickers or pictures and double sided tape to decorate your cabin door. Stateroom cabin walls are metal covered with vinyl. Some really strong magnets are great for hanging papers, clothes to dry, daily activity schedules, and if strong enough for anchoring clothes lines. You always get a terri robe so you don't need to bring one. You will have a combination room safe. The cruise ship lends you a beach towel to take if you go to a beach. Take good sun screen and insect repellant and pack them in plastic boxes or Nalgene bottles for the flight. Take extra glasses and sun glasses. A copy of your vision prescription has been a Godsend to travelers on several of our trips and could come in handy in some ports such as Hong Kong where glasses are inexpensive. There is a large lending library of books and DVD's on all cruise ships we use. I like to have my insulated travel mug. I rip a lot of videos to my computer with Handbrake to view on my iPad and iPhone 6p. You move videos on & off of your iPad through iTunes. In much of the developing world you bring your own toilet paper with you to public toilets so we carry a lot of small packs of tissues. On most cruise ship shore excursions you can leave your backpack on the bus when you get off to visit sites. Susan carries her own dual voltage curling iron. There are actually two hair dryers in your room, a good plug in one at the dressing table and a wall-mounted one in the bathroom. You might swap photos with other travelers by using an SD card or usb stick so carry a few cheap ones. One of the most important thing not to forget is to take some photo copies of your passport picture page. Because you use the photocopy of your passport rather than the actual passport (which the ship holds for you) you may still need your driver's license or other government issued ID at some money exchanges etc or if you have marked your credit cards CID. We always like to take seasonal stickers etc to put on our cabin door for a personal touch.
Medical Considerations
Be sure and take some bandaids. Carry medication for a common cold, for gastroenteritis, for cuts & scrapes, and for diarrhae. Carry several types of antibiotics. I like to have some Augmentin, Cipro, cephazolin, and some doxycycline. Take some handkerchiefs. When visiting malaria prevalent areas we choose to take mefloquin but some people have bad dreams on it. Don't forget that most malaria meds have to be started a week before needed and continued after the trip. Of course we needed malaria meds in French Guiana, Brazil, Sao Tome, and mainland Africa. At this time, the big mosquito worry is Zika virus in Brazil and there is no treatment so prevention of mosquito bites is very important with long pants and shirts as well as frequent application of insect repellant. The Ebola virus epidemic was conveniently declared over in the week before we landed in Africa. We have learned to get medical evaluation of infectious diseases in the area the disease was acquired as so very many local physicians and pharmacists know exactly what is prevalent in that area and it's treatment. I would rather have invasive or surgical care back in first world countries. Know what your health insurance will cover overseas. Oceania and Holland America have excellent physicians onboard. Take some laxative as you may be less active on a cruise than at home. Sea sickness medication would be a good idea as would cough drops, ear drops, eye drops.
Photography
We carry two Nikon D-SLR cameras (D7100 & D90)and take Nikon raw photos. Susan uses a 18-200mm lens exclusively and I vary from a similar Sigma lens to a Sigma 10-20mm lens. Using different lenses give us the chance to capture different views and particularly the 10-20mm lens allows me to capture buildings or rooms in their entirety without having to get too far back from the subject. We certainly do discard more of the wide angle pictures. The 18-200 is good for standing at a distance and capturing shots of people without being so very obvious. We have given up using lens filters as Aperture can simulate any of them. I occasionally use a circular polarizer when at higher latitudes but did not even take it on this trip. We also carry on our trips small point and shoot cameras that often we carry to markets and areas where we don't want to take our larger more visible cameras. In most of the world we use neck or wrist straps but in some parts of the world (particularly Brazil) it is dangerous to use a strap as we have seen several people hurt by the straps when their cameras were stolen. We saw a lady dragged over a block by a thief in Santerem because she had her camera strap around her wrist. She sustained damage to her wrist. We had been warned that camera theft was so common that it was dangerous to use the straps. We carry plastic bags with us for two reasons. When we take our cameras out of air conditioned rooms in plastic bags they don't fog up from the outside humidity. The plastic bags come in handy if it rains. We import our pictures daily to Apple Aperture and quickly discard (reject) the out of focus or poorly-exposed ones. Then we next pick the best of any particular shot. Be sure all of your cameras are set to the exact same time to the second. I recommend even fixing your iPhone's time to be your home time zone and then just have Aperture (or Adobe Lightroom) adjust the time to local time as they are being imported. Aperture handles the Nikon Raw files so much more seamlessly than the Photoshop or Lightroom we used to use but soon we will have to swap back to Lightroom as Aperture is being discontinued. The most common adjustment we make in Aperture is white balance. Many light fixtures that in the past were incandescent now have the energy efficient fluorescent bulbs or LED bulbs and need white balance changes made. Apple Aperture is no longer sold in the Apple Store and will soon disappear but you can import entire Aperture Libraries when the day comes that Adobe Lightroom is the only choice (? this year, 2016). When staying at a resort I commonly take a strobe with extension cord and macro lens but I usually take neither on cruises. There is a very good case for taking cheap point and shoot cameras for crime prone areas like Brazil and Benin. Take extra batteries and SD cards and keep them charged.
Computer & Phone
Be sure your phones, iPads, & computers are password protected when you travel and can't boot up in a way to bypass the login screen. That way stolen or lost computers or phones aren't a liability to your important data!!!
Both phone service and WiFi are available onboard at a cost. The phone service acts as a roaming service. We have Verizon and we have Verizon activate the SIM card for our iPhones for the countries we visit before we leave the United States. Verizon gives us the rates for the various countries and we keep them in mind. We use texts and I think Verizon's charge is 50 cents each to send and 5 cents to receive when out of the country. We seldom use our phones but carry them with us off the ship for emergency calls. The GPS function and compass feature on smart phones can come in handy as can the flashlight feature. If you will not have cell data turned on, you must plan in advance to have the correct maps in the system before visiting the country. The cruise lines give you a local number to call their port agent in each port. We seldom turn on our cellular data for foreign roaming. Verizon's texts come through WiFi so logging on to WiFi in coffee houses, McDonalds, or internet cafes often gets these texts. We vary as far as how we use the ships WiFi services. You can buy so many minutes through your computer or iPad. On some cruises we make sure we visit coffee houses or McDonalds when we are in port. Cruise ship internet gets better every year. We spent only about $15 on ship internet this cruise.
Internet we found in various ports:
Aruba: We had free internet at Subway in the mall near the ship.
Curacao: There was free port/tourest internet just off the ship where we were docked and in several places across the Queen Emma Bridge.
Bonaire: Good reception at Eden Beach and Resort where we paid $5 each for beach, pool, bathroom access, lounge chairs, and internet for the day.
Barbados: We had good reception at Burger King downtown. The internet password is on your receipt.
Devil's Island: none anywhere.
Tobago: We found slow free connection at the pier just as you turn left along the port building.
Belem: There was very good free internet in & outside the cruise terminal.
Recife: The city is constructing a beautiful new cruise terminal and has good free WiFi but on our day it wasn't connected to the internet.
Luanda: Walk to the Skyna Hotel downtown and buy a drink in the bar and the bartender will type the password into your device.
On this cruise we carried two MacBooks (laptops), an iPad, and our iPhones. This allowed Susan to type her story and me to edit pictures in Apple Aperture at the same time. We have taken only one laptop and used an iPad for Susan's Story on noncruise travels like our 2015 Bangladesh adventure. We frequently back up our pictures and Susan's Story to large SD cards which can be easily concealed and are faster than USB sticks. I love using Windows 10 utilities on my MacBook Pro using Parallels Desktop, especially set up as Coherence which allows the Windows programs to run on the OSX desktop. I use my iPad as an additional monitor using Duet and an Apple lightning cable.
Electrical
We take only appliances that will run on either voltage and since we are from the US we use small plastic adapters that turn the 220v plugs to 110v (NOT A CONVERTER). I carry a couple splitter cubes. We have seen people have power strips confiscated on cruise ships so don't take them. Some plugs only work when the stateroom lights are on or a room key card is in a slot in the room but not on our recent cruise ships. The Oceania ships have a shaver 110/220v plug in the bathroom. We don't need to take a voltage converter. Be sure and bring battery chargers for any appliance that needs one. Most modern chargers will run on both 110v & 220v but check before you come. There are hair dryers in Oceania ships. On all of our recent cruises we had a built in one in the bathroom and a good hand held portable 220v one for use out in the cabin. There is a wake up function for the phone so you don't need an alarm clock. In actually, we have evolved to ordering coffee delivered to our room as our wake up call which solves the ever recurring problem of frequent time zone changes. On Insignia this cruise we each had a 220v plug by each side of the bed and two 110v and two 220v ones on the dressing desk. The light switch for the bathroom is outside the door so to avoid awakening Susan, I put up a battery powered LED stick-on light in the bathroom. Don't forget appropriate battery chargers and cables!!!
Clothing
We have special travel socks and underwear such as those by Exofficio or Magellan that we can wash out daily and need very few pairs. These usually dry within a half day if washed in the room, thoroughly rung out, rolled up inside of towels, and hung up to dry in the stateroom. These dry more quickly inside than outside on the veranda. We also have travel shirts and pants (long & short versions of each) that dry this quickly when hand washed in the room. We carry a small Nalgene bottle (from REI) of concentrated washing detergent for this and I pack this Nalgene Bottle inside a waterproof box or larger Nalgene water bottle to avoid the consequences of a leak in route. There are usually laundromat services on cruise ships but be advised that these are closed if there is an outbreak of gastrointestinal illness on the ship. We had a great one on the Insignia and it was very easy to run iron clothes a couple times a week. Cruise ships offer laundry services at a charge. We have culled the clothes we take over the years to be those with the most wrinkle resistance and to dry the quickest. In many parts of the world, we really appreciate the secure zipping pockets of our travel clothes (safari type clothing). Don't forget your hat for sun protection. Much of our clothing has built in sun protection.
The more years we travel the more we find we can take less and less clothes with us on our trips. Oceania has no formal nights but I find my blue blazer appreciated at times. Holland America has one formal night a week but a suit is fine as very few formal clothes are seen on those nights. Some cruise ships are cold so be warned. Even if you don't plan to swim, take a bathing suit as the hot tubs and saunas are wonderful and you might need to work on your tan.
Packing
We like suitcases that will compress enough to keep under the bed so they don't take up room in the stateroom. We often carry a thin gym bag in case we buy items that will require another suitcase on the way home. On every cruise we take there are passengers whose luggage did not arrive on the airline and they are stuck without their luggage. We put a couple changes of clothing in our carry on luggage and we almost always go a day or two early so any tardy luggage has a chance to catch up with us. On the flight to catch our cruise I label each luggage item with our final destination for the flight (hotel name) because luggage could get mixed up on the shuttle from the airport (this has happened). When flying through remote third world airports we often choose to pack our clothes in plastic bags inside our suitcases as we have had our clothes soaked with rain or covered in dust in the past. Susan & I mix our clothes in each other's suitcases in case only one suitcase doesn't make the airline flight. I use Nalgene water bottles and plastic waterproof boxes to pack my fragile or liquid items.
Money
We have found that having a couple hundred dollars each in one and 5 dollar bills (or euros in parts of the world) opens up so many possibilities to get us good service, pay porters, and buy trinkets. We find out immediately upon entering a country how to tip and who. The US dollar is still king. We split up our credit and debit cards so if we are robbed we can continue our trips.
One of the most important thing not to forget is to take some photo copies of your passport picture page. Because you use the photocopy of your passport rather than the actual passport (which the ship holds for you) you may still need your driver's license or other government issued ID at some money exchanges etc or if you have marked your credit cards CID. I have records of credit card numbers and the international phone number for the card. We know which ones have foreign transaction fees. Before we leave on our trip we call the credit card company and let them know which days we will be in each country so they will allow the transactions. We still have cards frozen by the banks when we withdraw large amounts out of the country or make large purchases. This problem is easy to resolve by logging in to the card's web page and checking messages. Keep up with your plane tickets and any vouchers you carry with you. In Europe and Japan in particular be sure your credit cards have been upgraded to Smart Cards that carry the computer chip.
I scan all travel documents (airline tickets, vouchers, passport copies, drivers licenses, credit cards front and back, etc) to pdf files to be placed in "books" on my Mac, iPhones, & iPads in case documents are lost or stolen. Be sure these devices are password or pin protected and logged out when you aren't using them!
We DID NOT EXCHANGE ANY MONEY this whole trip! Dollars were just fine everywhere!
Transportation
We used no public transportation the whole trip until South Africa as we took Oceania shore excursions in most ports and walked in others. In many ports, where necessary, Oceania had free shuttle buses to town centers from the ship. We love to walk however!
Travel Agent and Guides
We love our travel agent Dianne Blackburn at Gateway Travel in Spartanburg, South Carolina. She usually follows our progress when we fly and has even called ahead and rebooked flights when she knows we won't make connections. We call her from all over the world. We have used her for over 20 years and feel she consistently gets us the best deals. Susan takes whatever deals she can find to her and Dianne tries to get a better deal. Even when we book a cruise etc we make sure Dianne gets credit with the Cruise Line.
