We were there last Thanksgiving week. We stayed Sat-Wed, left the night before T-day. It was crowded, but we went knowing it would be that way. It is completely do-able, just plan on getting to the parks before opening and taking an afternoon break, so you can stay late. Thanksgiving day thru Sunday following were extremely crowded last year, with the park at capacity most days. We would do it again without a problem, but would try to avoid the actual holidays.
