We *still* had a great time. Got there early - taking advantage of AM EMH at the MK yesterday and today, and then used the PM EMH at MK on Monday (Christmas) when we had a great time after midnight!
You have to expect the crowds and plan around them. See the hotels mid day, or go to a pool. We did Disney Quest which was crowded, but NOTHING compared to the parks.
MK was jammed by 10AM today; good thing we were there at 715AM.
