We usually go to Disney in the summer, since I have two teenagers (and one in grade school).
We've gone in Dec three times now, always the week AFTER Thanksgiving. As far as crowds, it was wonderful! Most rides were a walk on. (Magic Kingdom on Saturday afternoon was still busy!) The decorations are beautiful - and the Christmas tree at the Grand Floridian is breathtaking!!! Its really great! In 2000, it was nice during the day, but got kind of cold at night. In 2001, it was nice, warming during the day, just cool at night. In 2002, it was cool during the first day or so, but got cold for our last few days and nights.
This is our first time visiting in October! We'll be there Oct 13-18, and will do
MNSSHP on Oct 14, and possibly again on Oct 16! Its going to be a Mom and Me trip - just me and my 7 yr old to go trick or treating at Disney! Can't wait!! I'm just hoping for some nice weather for swimming!!! Also, we're trying to decide what we'll dress up as for the Party - I'll just be wearing a Halloween shirt, but she's trying to decide - princess or what??
Anyway - have fun choosing!!!
