Not for this year, but thinking ahead to next year we are tossing around the idea of going for my son's 5th birthday (and coincidentally my DH's 40-two days before and the day of Thanksgiving respectively). Looking at crowd levels though I'm seeing 8s.
We took my daughter for her 5th birthday and it was a wonderful trip. Her bday was at the end of September though so crowds were mostly 2/3-5. The kids are sort of expecting it since we did it for her. Will the crowds make it unenjoyable?
Re: Disney around Thanksgiving? Horrible idea?
Personally, I wouldn't dare go around the holidays. The parks get so crowded that they will close down in phases and guests won't be allowed in.
We pull out kids out of school to go to Disney.
