Sorry no party, but it is still one of the best times of year! We went as a family two years ago right after thanksgiving. We were not able to get together for thanksgiving due to work schedules. We found a great deal and we're able to stay at the Grand. All the hotels were were beautifully decorated, but the Grand was exceptional. It was the perfect way for us to kick off the holiday season. We were able drink mulled cider and hot chocolate by the fire place and listen to An ensemble singing Christmas songs and look at the HUGE decorated Christmas tree in the lobby. There was a life size gingerbread house in the lobby. even if you are not able to stay at the grand, I suggest you carve out some time to experience it. The parks are both decorated, however DL does a lot more in that department (although I personally love how they decorate cars land). I have not experienced it, but hear that the week betweeen Christmas and New year is the busiest week of the year. I personally would avoid this time, but have friends love the atmosphere of the park when it is crowded. After New Year's it let's up a little, but not enough for my taste. That second week in January would be my choice if you have to wait until after Christmas. Good luck!
