... hop on a plane. Yes, that's another vote for the week after Thanksgiving. I try always to go the week after Thanksgiving, and have never run into big crowds. This year, I'm arriving on the Saturday after Thanksgiving (which means saturday might be crowded, as the Turkey Day vacationers will most likely be leaving the next day) and staying for a week. The decoratiosn are up, the lines are down, and the weather is perfect, allowing for plenty of time at the pools and waterparks!
