Michelle, Christmas Day was our best park day believe it or not! We had lots of AK fun, but didn't even get over to Dinosaur or that area at all.... I have not been so soaked at WDW before. It was crazy.
My DH & I were at AK on Christmas, also, though we were there earlier than you - we missed the rain. There were a TON of Asian tour groups, but other than that, the park was dead. I guess most people were exchanging presents, or were at the MK for all the festivities.
Later that week, we were at Epcot, and lines were incredible. We Fastpassed Soarin' right away, which was good, because it ended up being a 160 minute standby wait by the time our Fastpasses were up. Incredible... I've never before had to wait a full 30 minutes just to ride Spaceship Earth or Journey Into Imagination!
Apparently WDW hit all time attendance records over this holiday week, and I could tell just by the traffic on 192. We live off of 192, and starting around 10 every morning, it was incredibly congested. Now I'm glad that we have our anniversary (when we do our big yearly GF trip) in the summer, though I used to think that would be the most crowded time. We're doing BC concierge for the first time over MLK weekend, so I'm hoping crowds won't be too bad over that holiday weekend.
Cheers!
