The handbook gives you good guidance as to what to bring with you, but there are a few things that our experiences have suggested might be useful. But don't pack too much! Remember: storage space is limited, and dress on the ship is aggressively casual. There is a small store aboard, and there are always opportunitites to pick up things in ports. Herein, our personal and limited list of things that you might want to bring with you:
ziplock baggies
Off!
Pepto Bismal
sunscreen
pens
Sharpie
scratch paper
French press coffee maker
travel coffee carrier/mug
coffee
work-out clothes
corkscrew
magnets (no tape allowed on walls)
masking or box tape
fold-up umbrella
gifts for children in countries: stickers, balloons, crayons, etc.
European two-round-prong plug (your cabin has normal outlets; the rest of the ship is European)
extra passport photos (for Cambodia visa, for example)
scissors
thank-you notes/notecards
stuff for the auction
3 1/2-months' of meds (your doctor will authorize it)
Don't bring a ton of clothes; you can have stuff washed for $7 per bag (ironing is slightly extra; no dry cleaning). Ship life is casual. It's COLD in the Union, so bring a sweater or sweatshirt (or buy one of the Semester at Sea products on board). There are two dress-up events (business casual: Captain's Dinner and Alumni Ball).
And now, wise tips from previous voyagers:
Itty Bitty Book Light
Travel alarm clock
Small binoculars
Plug-in night light
$50-$100 in local currencies (avoid long lines of students at ATMs)
suction hooks for back of bathroom door
empty light-weight duffel bags for trip home
hand sanitizer
small toilet paper for in-country use
small first aid kit
Woolite
external hard drive to back up (if your computer crashes, you lose everything!)
zip drive
Clothing note: on the fall 2009 voyage, China was COLD (very cold).
