Check the website, I'd just set in the seats
There are very nice seats, and no reason for a blanket.
There is a long list of prohibited items in the FAQ section of their website, but I don't see blankets listed.
I've never taken one, but I would imagine that you could. There's a strip of grass along the seats that I've seen people sitting on. Wish I could tell you for certain, but I'm not 100%.
There are seats.
