Bought 4 tickets for Hamilton in Chicago for our 25th anniversary. Drove 5 hours. Checked into hotel. Went to theatre. Tickets they sold us didn't work. The ticket office confirmed someone else already had tickets WE bought! Customer service offered us 2 tickets in balcony (inferior to what we bought) and I guess the two people who came with weren't supposed to see the play. Had to buy 4 tickets (not together) for matinee the next day. I asked how could they sell tickets they didn't really have and they said they wouldn't know about it until we showed up at theatre. I told them that makes no sense to me that they wouldn't know. Bad business model if that's true! Horrible experience!
