We were there a couple of New Year's Eve. The first one, we avoided the parks altogether. The second time, we did Animal Kingdom first since they closed early. My husband and I headed back to the room. My son and his family and my mother-in-law went to MGM so do a few additional things. They loved MGM and wished they could have stayed. They were given hats and noisemakers and said it wasn't crowded at all (it was around 4:00 when they got there and about 8:00 when they left). My son thought that since the TV coverage is focused on Magic Kingdom and, to a lesser extent, Epcot, MGM was relatively ignored.
