Hi! We went in July 2006 for my 4 yr old's wish trip (she is a cancer patient). Of course, everything was provided for us but I can tell you a couple of things.
First, I know it is SUPER crowded during the holidays. They have a great Christmas celebration, not sure when it starts, but I would LOVE to go back then. I think it is pretty balmy still in November, so the weather should be good!
Definitely get the Park Hopper - we went to Magic Kingdom the first day and stayed there until after the fireworks. After riding the ferry back to the parking, we didn't get home til almost 1 am!!! The next day, we went to MGM, then back to MK and watched the fireworks again! The 3rd day, we went to Universal (separate park completely), and ended up where? MK! We didn't stay that night though! LOL
The 4th day was July 4th so we definitely wanted to be in the MK for the fireworks. I don't think there is anywhere else in the WORLD that has better fireworks ANYTIME than Disney on the 4th!
Be prepared to wait in lines, take drinks in a diaper bag for your little one, they won't care about that, and expect to rent a stroller every day. It is a TON of walking.
Geez this is long! Sorry - check out allearsnet.com - it is written by Floridians who have season passes and have been going to WDW for years and years. That's where I got a lot of info.
HTH!
