I have seats in the handicapped section, do I have to use my wheelchair?

Usually ticket master or telecharge will say on the website what seats are actual spaces were you'd put your wheel chair as the actual seat

I also suggest calling the theater. I also suggest bringing wheel chair no matter what the theater might tell you. The seats are small and the spaceing for leg room is ridiculous

Yes

When we went a lady in wheel chair sat at end of row with her friend. I suggest you contact theatre.
