Who said Disney had to be fun?
There is still Universal down the road and many others.
Just trow Tapestry of Nations in front of me and you'll keep me entertained for hours (kinda like a box and a 5 year old).
The other thing is the Pop Century hotel, which will open latter this year (supposed to open this month, but 9-11 and the travel decline postponed it). It can easily hold all of us and is located next to a place bigger than the Exploraion parkinglot, Disney's Wide World of Sports. This place is huge, convert some of the colusums, parks, and stadiums and it'll defianly be the Nats!
