Looks like you had a great trip!! What type of camera were you using for your underwater pics? We are taking our first Disney cruise next June and I've been thinking of getting a waterproof camera to use while on Castaway Cay.
It's a Fujifilm XP170 - there are several in the XP series. Most of them it's just what depth they are good for. Pretty decently priced. There were a few people that had them there.
