Went to WDW in July 2003, and although I hear that the parks were crowded, we did not suffer for it. Only one ride did we wait more than 5-10 minutes for, and it was the one ride where we deviated from TGM's advice, since DSD wanted to do something very badly. So, to accomodate her, we changed our plan. Families do that
July was also very hot, but we left the parks at lunchtime to go for a swim at the resort, so we avoided the hottest part of the day. Didn't feel like we missed out on anything. Did we do every attraction? No, but then we weren't going commando. I feel that we were able to do just about all that we wanted to do, and still have some down time. Things that we could not do (i.e. E-Night), because Mother Nature decided to let loose, were things beyond our control, so we didn't get bent out of shape over them.
DH had been very apprehensive about going to WDW in July, because a friend of his at work had taken his son in July 2002. DH's friend reported that the parks were mobbed, the water parks were mobbed, and it was exhausting, and never again.
I am certain that if I wasn't armed with that info, we would have suffered a similar fate, since my DH and DSD have quite different habits then the ones we were advised to do by TGM.
Fortunately for us, DH went along with it when I told him (yes
told him) what our daily itinerary was (maybe it's the Teutonic in me?

). After Day 1, he didn't question my itineraries at all. We had a great vacation, and my DH was able to brag to our friends how we didn't wait for anything, got to do lots of stuff, and still had time to relax at the pool.
I'm going in January 2006, and am undecided about whether will use TGM since I predict low crowds, but since we are bringing friends who have never been to WDW, I may utilize TGM anyway. We'll be able to maximize our time spent in the parks and do all that "first time" stuff.
P.S. If you don't want to use TGM, fine with me, since it means that many fewer people who "zag" when we're zagging!
