I have a blanket in my backpack am I alllwed to bring backpacks here?

I'm pretty sure you are, but they might have to check it's PRETTY big. However, that is pretty unlikely. So, have a nice movie with your blanket!

You might want to down size that blanket to a throw blanket and I'm pretty sure you could probably bring that in there cause it does be pretty chilly in there Enjoy.I Did.

Backpacks aren't allowed, bring a purse lol

I believe they do bag check
