We're headed down at Christmastime this year--a first for us. We're experienced at WDW, but never at Christmas.

I have some time set aside to visit a few of the resorts that decorate for the holidays because I have heard they go all out.
My question is:
Which resort lobbies do I HAVE TO visit?? What are my "not-to-be-missed"?
We're staying at POR, so obviously we'll see that (if there's anything to see) but I have a soft spot for Christmas and how people decorate and I can't wait to wander around property and see it all!
Help me out, SubSonic-ers--what are your suggestions?
Thanks!
