I'm going to be in the city for one evening for a quick business trip and would love to see Oh Mary, but I'll be back Nov. 5 as well, so could see it then instead. Is Once Upon a Mattress worth seeing next week? I'm a huge fan of the cast, but I don't know much about the show.
Oh Mary is the one to prioritize since it's better. You can still see Once Upon a Mattress on November 5 (or can you get cheaper tickets for OM in November? That's the only reason I can think of to delay.) Cole hasn't missed a performance, but with Covid and who knows what else could happen, I would do OM first (and then if they're out next week, you can try again in November).
