Are seats handicapped accessible, in particular, in the balcony.

It is a great place to go! The floor seats are accessible but I don't think they have an elevator. However the best way to check is call them.

Front row of balcony is accessible

I would say if you can't walk up two flights of stairs then no. But the lower level is accessible

I don't think the Calvin has an elevator. If you can't walk up stairs, I would say balcony would be off limits for handicapped.
