If we purchase tickets at the box office rather than online do we have a choice of the remaining seats or do we sit in a designated "box office purchase" area?

All open seating, as far as i know.

Open seating. At the dooe is Cheaper than buying them on line too.

Buy tickets at the door 5 for $35. Open seating.

To my knowledge, it's the same as online seat options. I've never bought tickets online, and I haven't noticed only being able to pick from a certain section of seats.
