Not my first date in general but for my first date with this girl.

I invited her the other day to go to the movies with me tonight, but I didn't tell her which movie theatre to go to. I just said Tuesday at 8 to which she happily agreed. Should I text her at 5 and say something or assume she knows which theatre to go to? I think she knows it's the one across the street from my apartment but I'm not sure. Should I wait to see if she texts me first to check in?
