I have reservations for Sun-Tues 12/18-12/20. During this time I know it is crowded, I don't have to pull my son (10) out of school and I have the week off. I have been toying with the thought of going the Thur-Sat 12/8-12/10 only because I think it might be slightly less crowded. Only problem is that I would have to pull my son out for 2 days (which is fine for him but I hate for the school to lose money) and I would have to get 1 day covered at work. So, which dates would you pick? I guess my main concern is crowds.
