How early should you arrive to a sold out show to get a good spot on the waitlist? What’s the probability you’ll get in? Does anyone scalp tickets?

At least an hour before, not sure about the scalpers.

30 min is good enough. Extra seats. Or extra tickets, yllthe door peslrson has all the good info.

I would say at least 30 mins before but they don't let people into the main room until right before. Good prob. Don't know about the scalping. Ask for tix whem you get there as they might have extra tix still.
