First date help

Sophia • 6'2 Single and ready to FRICKING mingle
I'm going on my first ever date tonight (I'm 18) to the movies. (He works until 10 so that's really our only option) I'm really excited I just need to know its it's too early to hold hands during the movie since it's a first date, we will most likely kiss, and what to say at end of the date before we part ways?
I've never done this before so idk how to do this
