"Aren't you afraid all those kids will drive you crazy?" Not at all. Disney has an excellent kids program that is tiered so that kids of similar ages are grouped together and the activities and facilities they utilize are targeted to that specific age group. Kids love their groups and the Disney staff does a tremendous job keeping them busy and happy. Disney also has designed its ships so that there are distinct areas and events for kids, for families and for adults only.
Finally, while the kids are older and Disney is certainly nothing new to us given we're long time Disney fans, we still feel the Disney "magic" and enjoy the familiar characters, stories and the joy of feeling a little bit like a kid again.
