Which park Thanksgiving Day?

Universal Studios or Islands of Adventure? Will they both be swamped? We are planning to hit one at opening and then leave. Thanks in advance for any tips on this one.

This year we went to IOA on Thanksgiving. I didn't think it was that bad compared to all the days surrounding it. We had dinner reservations later in the day at Mythos, so we went to IOA before that.
