Whether you should do Thanksgiving dinner at Aulani or some other restaurant will depend on how much you want to spend. For the holidays, most restaurants offer a prix fixe meal and reservations fill up quickly. While I haven’t done Thanksgiving at Aulani, I’ve done Christmas several times. In addition to it’s regular restaurants, Aulani typically has a holiday meal that can be ordered for the room or a dinner that requires reservations. Roy’s Ko Olina also typically has a holiday meal. You may also be able to do a luau on Thanksgiving. If you haven’t already, I would suggest calling Aulani closer to Thanksgiving to see what is available and searching restaurant websites to see if they plan to offer a special menu and if reservations are required.
