Is it possible to show up on person and buy a ticket the day of the performance of the nit cracker. Presently,schedule is unclear.

Yes you can but honestly don't know if its different for each specific show or event! But a chance they could be sold out.

I would say probably

Yes, as long as the show is not sold out.

Yes

I would call them directly, most times no.

You dont have to buy in advance but cant. Say if tickets will be left
