My advice is to plan to split up and meet back at lunch or a certain place. It's so huge, you will want to spend time on looking at what you are interested in and not waiting for a friend to check out something closer. We spent 4 days there and I was never bored. Be sure to tell your bank that you are going and that there will be charges from all over the country. A friends Visa was put on hold because of charges from the East Coast and the West Coast within about 30 minutes. She had to stop and get it straightened out before she could charge more.
