I stayed at POP this past Christmas, and I had the best vacation ever. I had heard horror stories about crowds, etc, but I enjoyed every day in the parks. The best plan is to get up early, leave the parks in the early afternoon, and go back in the evening to enjoy EMH. Even during peak hours, I did not think the parks were unbearable because you're not dealing with the heat. The decorations were amazing, and I am already doing the math to see if I can afford next Christmas at WDW.
