We went in 2011 the week after Thanksgiving and LOVED it. By Disney standards, the crowds were non existent. With the exception of a few things like Soarin, TSMM, and a couple of other big attractions, everything else....literally....was 5-10 minute wait times if not walk up. We went to each park based on EMH's and on the days without EMH, we did Universal and Sea World. We easily could have done both universal parks in 1 day but opted to take our time and split them up. We were done by 2 or 3 in the afternoon. I don't think we waited longer than 5 minutes for anything there. Sea World was disappointing, but the same as far as crowds went. It's definitely our #1 time of year to go. Now, that's not to say that's how it will be this year.
