Be aware though, there are some rude people who will park in front of you (mainly suvs) and face backwards. The parking lot is not flat, the parking spots are slightly tilted upwards so your car is aiming up at the screen.
Now, you just pay for 1 ticket and its for 1 movie.
It used to be that 1 ticket allows you to watch both movies but this changed a few years back. Its a great place to watch a drive in movie.
