You could ask to sit at one of the picnic tables in the back of the room, though I've never actually seen anyone sitting in them.
You'll probably sit with another group in a car, it'll depend on how busy they are.
The cars all have, I want to say, 3 or 4 rows of 2 seats in them. We're always a party of 2, it's not awkward at all with another group in front of or behind you, it's not like you're all at a big table together or anything. You're not really talking at all because of the movies, and you're further away from each other than you'd think because of the counter in front of you.
