We were there from 12/29 - 1/4, OMG the crowds were ugly, but we didn't do the parks. Only 3 times, and one night was at the MK from 11:00pm - 3:00am. We got a 2 bedroom at VWL, spent alot of time in the room/at the resort. took a sleigh ride one night, watched the fireworks from the Contemporary. On 1/2 maybe, we went to Epcot it wasn't bad, then MGM had late hours for resort guests, NEVER AGAIN! that place was nuts, I am glad we saw the Osbourne lights, got some pics of the kids and caught Fantasmic, but couldn't get near RRC or TT. Lines were insane. Why they don't keep the enitre park open I don't understand. And why they hold fantasmic at closing I don't understand. We left! Now on 1/3 we went to the MK and it was very nice, but we headed over around 6:00pm till 10:00, and no lines, except Space Mountain.
I want to go again next year, mostly for the fireworks! If the weather is always like that, (75+ during the day, and cool at night) we will go everyyear.
We also went to Blizzard beach on 12/31 and no lines, it was great!
