Yeah, I took my three to Disney World .... once. They didn't ask to go back either. And it wasn't a disaster, just hot, crowded, expensive, and not really fun. We'd go to the park near Cincy each year for free anyway, it was sufficient. King's Island. When they got old enough, they went there on their own without me, if they wanted.
There is this French beach resort in South Carolina that two of them liked.
