A long shot I know. Got a spare adult ticket near the front of the middle of Upper Loft today if anyone wants it. Form an orderly queue.
Gave it to some bloke queueing up who then didn’t sit next to me so had two seats to myself right in the middle of the third row of the Upper Loft. Happy days.
The Box Office are very good at buying back spare tickets when people don't turn up. Happened to me a couple of times. Just have ID and the card you bought the tickets with and they will refund you on the card.
