My husband and I love Walt Disney World! There are a lot of CF couples that go there, too. It is SO not just for kids. We love the rides, the great food, the beautiful scenery, and all of the fantastic shows. We stay at the best resorts - the more you spend, the fewer kids there are around.
Disney is SO good at keeping the irritation of children to a minimum for adults. The place is awesome.
A great CF activity is the tours. They're pretty spendy, but there are hardly ever kids on them. Just adults. You get to see all of the behind-the-scenes stuff. We saw costumes being made, the huge warehouse where the Christmas supplies are kept, and watched the Disney princesses doing their hair. It was great.
Our goal is to visit every Disney in the world.
