The Pit at Cynthia Woods Pavilion is relatively small - holding just 160 seats when there is reserved seating. With chairs removed, the Pit holds a few more people, but not many.

Doors for this show open one hour before the event (opening at 6pm). With fewer than 200 people vying for a good spot in the pit, you don't have to get there incredibly early. If you are very concerned about not being able to see, we recommend getting to the venue at around 5pm to line up for the pit.
