We've been to WDW three times during Thanksgiving with my whole family- parents, brother and his family, etc. We kinda made it a tradition to eat Thanksgiving dinner at Crystal Palace. I think most places serve the traditional turkey and dressing. LTT is the most popular and I think it usually fills up quickly on the 90 day mark. ( I know when I was calling for CRT one year, the cm said LTT had already filled up too!) We like the fun atmosphere of CP so we go there. However, know that MK really gets packed on turkey day!!! I mean wall to wall people. I know it was closed to new visitors around lunch one year b/c it was at capacity. So you might want to try another park if you don't like crowds.
