I agree with Eric. Take your laptop so you can transfer your photos and catagorize them while you still remember where they were taken. Wireless is throughout the ships so you can upload to Shutterfly or some other program for showing a few photos to friends & family. I could load about 20 photos on Shutterfly and add them to the share site in about 5 or 10 minutes on the ship (compared to a minute or so at home.) Additionally, with your laptop you don't have to wait for an open computer lab machine in order to be online.

There's no problem taking a laptop overseas anymore - you don't have to declare it in any country unless you plan to sell it there.
