I'm at Disney this week - staying in a Windsor place and I also agree they are fantastic and a much better option than staying at the resort. I'm 42 and this is my first Disney trip ever.
Magic Kingdom - what's the big deal? I guess it was awesome in 1970, but it's a lot of crap. I grew up going to Six Flags in Atlanta and it was a lot better than Magic Kingdom.
Animal Kingdom - TERRIFIC. We all enjoyed Everest, the safari, the Kali River Rapids, and the food at lunch was MUCH better than Cosmic Rays at MK.
Chef Mickey's: WTF. It's a buffet. Great. Mickey, Minnie, Donald, Pluto, and Goofy rove about to take pictures with the kids. Great. It was $260 for 5 of us. For a buffet. With 2 (total) glasses of wine. Not worth the cost, but a decent dinner I suppose.
I cannot imagine coming here and doing this more than once every few years.
