Help! Need to sell HP and the Cursed Child

Hey i purchased tickets several months ago for Harry Potter and the cursed child and i just realized the show is tomorrow and I never sold the tickets. I have 6 tickets (to part 1&2), and i just want what I paid for them, which is $100 each. That’s for both shows, part one and two. Anyone know how i can sell them on such short notice? I’ve already contacted everyone i know In New York. It’s too late to return the tickets at this point and Ticketmaster won’t let me relist them. Any help is appreciated! Thanks!
