once you have had pit.... nothing else is an option ;)
If you try to buy 4 and there are only 3 available then, yes. However, if there are a sufficient amount of tickets available in your price range, then you will probably be okay. Pit tickets are selling out super quick so it may be more beneficial to just go for the reserved seating. Either way, it's taking a chance and your decision.
will buying 4 reduce your chance of getting GA? or do we know if there will be GA tix?
Up to 4 tickets per Church Choir membership.
