We were just there Aug. 1-8 and we have never seen it that busy! We went in July in 2001 and Aug. in 2002 and we don't remember it being nearly as busy! We assume lots of other folks got the same great discounts we did!
The most crowded park was MK with the other parks being busy but managable.
I'm afraid most of the summer seems to be equally busy with the exception of late Aug. when most kids have returned to school!
We didn't let it slow us down, just used fast pass, new what we really wanted to do and slowed down a little this trip!
