Purchased voucher on Groupon, what do I need to do to make sure we have seats for the show we plan to attend. Can I come in prior to event and get tickets in hand or what ?

Call and make a reservation during business hours

Just bring a printout of your voucher. They will honor it. Plenty of seats, but it's first come, first pick on where you sit. Never had a problem here.

Call and make reservations for the show you want to see. Check your voucher as it has specific dates you are allowed to use it
