Need more tickets for grad group G

I got 3 tickets for my family because I was originally told by the others they unfortunately cannot make it, however I have now been told they can make it and would like to attend and group G is currently sold out. Hoping there are grads out there in group G who have extra tickets and are willing to transfer them over! I know it’s a late notice but if there’s anyone who can help it would be greatly appreciated! Thank you!
