Monday, Tuesday, and Wednesday are relatively quiet.
Thanksgiving Day was busy, but me and my boys hit MK at early entry and were the 2nd ones through the gate and by hustling, and using Fast Pass effectively, we rode Space Mountain, Carousel of Progress, Buzz Lightyear, Splash Mountain, Haunted Mansion, Big Thunder Mountain Railroad and Pooh before noon.
The weekend before was somewhat busy, but not terrible, and the weekend after was the same.
Actually, the worst part of our trip, crowd wise was the drive home on the Sunday after Thanksgiving! 45mph all the way to Atlanta on I-75N. A 10 hour drive turned into 13 hours!!! It's a good thing we went to Ocala on Saturday night, or our 12 hours would have been 16 hours!!!
The resorts were full the entire week and when we checked in on Friday night, our room assignment was not very good. I would recommend an early morning check-in to get a decent room assignment.
