Our Disney cruise was to Alaska, so the kids didn't really use the pool (some did, mine knew it was too cold...when the lifeguards are in snow jackets, it's too cold ). The shows were good and my kids liked the kids club (the younger 2, who were 7 and 3.5 at the time). I never went with them, but I know there were open times. My middle son would stay forever, my youngest...they would just call when he was done and ready to come home. My older son played soccer on the sport court the whole time...he was old enough to sort of take off on his own. They loved the arcade, loved the shows, watched movies, played shuffleboard, ate ice cream, just took walks. Only my youngest was into characters. They all said it was their favorite vacation ever (at the time...my oldest now says this year was the best vacation ever). They want to do Disney cruises all the time now. We did a Royal Caribbean this summer (Mediterranean) and they liked it a lot , but would all prefer to stick with Disney for future cruises (thinking of Northern Europe in a few years). What there is to do will probably depend on the boat...the Alaskan boat is a smaller one...and how much time at sea you actually have to spend on the boat will vary.
