Wow you night owls beat me. All the comments were right on. I with Mattox like the Fuji camera and by all means buy them at home and take them with you b/c they are very expensive on the ship. Wal- mart, any sporting good store should have the water proof containers that go around your neck.

My husband and I did the same thing as Baby Doll. We kept our passport in the safe when we went to the non-US ports. We of course needed it for St. Thomas/St. John. My husband found these wonderful cloth pouches with Velcro and a zipper for us to keep our Sail & Sign Card, I.D. and cash in. We also took a waterproof camera. (Which was really cool, because the water is so clear you can take pics in the water!)
Just a note on using a digital camera with a underwater case. I tried using a Nikon 3200, a small point and shoot camera with a underwater case. I paid around $120 for the case and tried it on a couple of cruises. The camera generated so much heat closed up in that small space that it caused the glass in front of the lens to fog when in the cold water. Also after 20 or 30 minutes the camera would overheat and shut off.
I may try one of the disposable cameras on the next trip.
On the photo ID, you will need some sort of photo ID along with the S&S card. This is for the authorities in the country you are visiting. They will need to see this before letting you go back to the ship. All they require once at the gangway is the S&S card.
