We went to WDW last week, from Sunday through Friday. It was the second time we had gone this year, the first being from Feb 29 through March 4. We had never gone the week after Thanksgiving before, but several friends of ours had over the years. We had actually taken their advise of it being slow and a great time to go.
I found Epcot to be much busier than when we went in Feb/March, which surprised me. There were definately more people there on both days we went last week. Twice I saw lines for Figment being 20-30 minutes. Living with the Land was 50 minutes at 11am and the FP line stretched to the entrance to the table area near Soarin'! Spaceship earth was 45 minutes one day, and Test Track 85. FWIW, the Future World east & west did get less crowded after the world showcase opened up at 11am. FPs, going at rope drop and a good strategy meant that we got to see and do everything we wanted to do. But, what we were able to accomplish in one day back in Feb/March took us two days this time. FWIW, my wife's theory is that the Candlelight Processional caused the increased crowds. She heard several people say that the only thing they came for was to see the Candlelight Processional.
MK seemed to be about the same or maybe a little more packed than before. Again, FPs, a good strategy and rope drop allowed us to see and do everything we wanted. We went on party days, and the crowds did pick up after 4pm when the party crowd was allowed to come in to the park.
DHS was a little busier than it was back in March. But, we were able to see and do much of what we wanted by keeping our same overall strategy. But, when the additional lands are opened up, its going to make it a two day park.
We didn't go to AK, so I can't comment on what the crowds were like there.
Compared to our friends experience, the week after Thanksgiving is now much busier than when they had went. I'm not sure there's going to be slow times anymore. Disney seems to be wanting to fill those slow times up. Also, I wonder if Disney intentionally or unintentionally wants you to spend more time in the park in order to get everything done that you want to do? Even though
ticket prices between 5 and 6 days weren't much of an increase, the longer you are in the park, the more you are buying food, souvineers, drinks, ice cream, parking, etc.
