Yeah, I may be there... :P
Just so you know, there definitely are no plans to close the show after May 27. You can take my word for it, since I'm in the show! The Ticketking website is just selling tickets up to May 27 for now, but they'll add more dates as tickets continue to sell. It seems they're marketing it as if it's a limited run, just to get people to buy tickets in a "rush".
I kind of thought it was premature to be ending the show so soon.
I got my information from the acctual WWRY website, but i can completely understand that not everything is booked yet.
