Help with date!

I'm going out with this guy (oh my god he's absolutely stunning) we've gone out a few times and this time we'll be going to dinner then driving out to a beach outside town to stargaze (the beach also has grass and picnic tables and all that). (I planned this date) It's freezing here so I happen to have two vests that are like battery powered electric blankets. I was gonna bring like another regular blanket and some hot cocoa in an insulated mug. We probably don't need snacks since we'll have just finished dinner but is there anything else I could do to make this date nice?
