I would maybe reconsider having your 11 y/o do the Pirate Cruise (along with your 9/yo). When our three kids (DS 9,DD 6, DS 4) did it last time they 'all' enjoyed themselves. My older son helped out his younger brother, and my daugher quickly found another girl to buddy-up with. I also saw a couple of kids that looked like they were a little older than my older son. I think your decision should depend on whether or not you think your kids would enjoy a Pirate Cruise away from mom/dad (1 1/2 hrs) on the lagoon looking for buried treasure. To me I defintely think they would enjoy it, and I don't think that they are very strict with the age limit.
