Is the seating first come first serve or do they go by the number seat on the ticket

Usually first come first serve

We had reserved seats for Paula Poundstone. Beautiful theater.

For concerts typically first come first serve

Depends on the event.

Not much of it

I believe it depends on the show. It should be specified when you buy tickets.

Concerts are usually first come first serve for balcony

For the concert i went to, general admission on floor level, and seating on upper level.

Depends on the show. Each show is slightly different from my experience.

It may depend on the type of event. But for the things ive gone to be it has been first come first serve.
