We were at wdw 12/27-12/30 and it was packed but that was to be expected. The overall trip was awesome my 2 & 4 year olds had a blast! Our first day there we were there for the park opening at MK which was cool and the kids loved it when all of the characters arrived on the train. The key is planning we went into the MK at 8:00 and went right on Dumbo 3 times, Peter pan twice, Pooh twice and the tea cups and big marry go round 3 times in the first two hours. Then it got packed so we just went slow and then went back to the dolphin for a swim, then back at night.
