Is this a spectacular not-to-be-missed event?
I can't stand Orlando/Disney/Universal blah blah blah theme parks - I've been there too many times. I've always been fond of Epcot though - it must have been the food. :)
If it's fantastic, I'd reconsider driving up there. If it's nothing but mobs of people slugging wine ("do you have any dry whites?") and pushing through crowds to get more more more... I may pass.
