There are the same number of events each day, and it lasts all day. The list of the athletes attending will come out closer to the weekend. I don't remember any special meals.
There are interviews with athletes, live shows, all kinds of different things. You will get the schedule when you walk in the park. I can't even remember who all we got to see. Usually all sports are covered including olympic athletes. And go to WWTBAM-PI. We had a great time watching Stuart Scott and Dan Patrick play. It was a hoot.
Some interviews take place under the big hat. Others are held in different theaters.
