Our thinking is, everyone that already RSVP'ed has a +1, right? And not all of the +1s are going to be used. So if you're without a way in or have a +1, simply write your situation and email address in the comments for people to see. The rest is up to you. Ultimately, we just want everyone to have a good time and get in to the show they want to go to. Or go somewhere else that is cool too.
Best regards and stay safe!
