We went the 2nd weekend of December in 2004 and the 1st weekend of December in 2005. We were only there during the weekends (Thursday to Monday) and found both times unbelievablely crowded. In 2004 MGM closed due to capacity that Saturday night and we waited to get in for a hour after the crowds thinned out. So the next year, 2005, we thought we would choose the first weekend....wrong. That is the weekend that they tape the Christmas parade. We were at the AKL and they were sold out. (I think a lot of folks from the taping were there, as we saw Vanessa Williams and family walking out as we were coming in after she did her taping at MK that day). I believe the weekdays HAD to be lesser in regard to crowds. We were only there during the weekends, arriving Thursday and departing on Monday-noonish. We encountered the Pop kids in 2004, but had no real impact on us, since we were staying at the BWI in 2004. People kept talking about how light the crowds were in early December, but during the last 2 years we just didn't see any light crowds and have crossed December off of our list.
