My son is also 11y/o and last year he went to the programs sometimes, but found them too structured for him and his 12 y/o friend he meet. They hung out all the time day and night, webrought along our walkie talkies and stayed in contact. This allowed me free time and him to have some space. It depends on what you kids are like, if they like camp type activities with a counselor then they will love the groups, but if they are indepenant and like to do things at their own pace then there are plenty of friends and so much for them to do on board. We had the rule that we would meet before dinner and get dressed then go the shows, before and after that it was free time. If it wasn't for the Disney atmostphere and all the friends he meet, I never would have let him out of my sight. However this arrangement made for a great trip. Of course on the islands we spent the day together. Any other questions i would be happy to answer.
