Our experience this year convinced us to NEVER visit again during this time.
Thursday before: MGM, very crowded, Early Entry plans worked until 11:00 a.m., long waits of over an hour w/o FP, difficult to access characters.
Friday before: MK, very crowded, Early Entry plans worked until Noon. FP @ 1:00 p.m with 9:00 p.m returns, rides crowded even during parades.
Saturday before: Disney Quest, crowded, hour waits, enough said.
Sunday before: Off-site @ NASA, great time, low crowds, highly recommend.
Monday: Epcot, moderately crowded, Early Entry plans worked. Encouraged by the attendance @ Epcot we ventured to the MK around 2:00 p.m. Big Mistake!!!!!! The entire park was near gridlock. Full of mean, nasty people pushing & shoving. We were only able to ride 3 attractions the rest of the evening - should have stayed @ Epcot.
This was the first time I've ever been glad to leave MK, such a disappointment.
