I concur with Rodica. It will be VERY busy, even with FASTPASS you will not get to do all the attractions that you may have planned for.
They are open on Thanksgiving day, but keep in mind that will be crazy crowd it. Not worth it. If you come mid-week, 20-30 min lines everywhere. Come on Thanksgiving, and expect at least 90 min wait time for each ride. I'm sorry but Alfonso Estrada is wrong. They are not open 24/7. The Park close at 12 midnight, every day.
