I think it would be a bajillion times more fun without kids... you can't ride any of the cool rides if you ahve little kids in tow.
We are taking the Munchkins for their first visit in May, and as I was on the phone for over an hour with the Disney lady, I thought "I am spending damn near half my annual bonus on a trip with my kids. C and I could go to Europe for what this is costing me. But hey, it's the Happ-Happ-Happiest Fucking Place on Earth", right?"
So if someone else is footing the bill, hell yeah.
