I am trying to call as I MUST make sure I'll have a chair. Line has been busy for several hours. Is there another way to contact them?

There are 2 person benches a bit low. Standard folding chairs are available, just ask.

They are very accommodating, they're are plenty of chairs

Just like everyone stated, there are chairs, if none just wait till next showing

yes, there are a few chairs and some benches. The benches are uncomfortable even with the cushion. there were few chairs available but the exhibit lasts about 30 minutes then some chairs will open up. There is a bar area right before entry so you could wait there till the show changes. good luck.

There are chairs and small bendhes
