Do we need reservations for Paint your Wagon?

You don't need them, but I'd recommens buying tickets in advance! Some screenings end up selling out fast in advance, and this could be one of them.

Better to have, than to not be able to get! Since designed to allow drink & dine, while watching movies, not as many seats as other cinema's same size. Plus most movies that sell out there, are posted hand written on a sign, placed by front doors & rarely is website updated that fast. So best to buy in advance & know you'll have a ticket!

Dean's right. You never know.
