I really enjoy going to the movies here. The prices are much lower than what you would pay elsewhere to see a movie in Las Vegas, and often you are paying to see a double feature!
As you would expect with an older facility and lower prices, things are a little run down. Most of the screens are just fine, some are slightly backlit by local light pollution (such as the fiesta casino). I personally have never been bothered by it.
Make sure that you take whatever vehicle you have access to with the highest ground clearance - the parking spots are angled for a good viewing experience, and this can make driving with cars low to the ground sometimes sketchy.
I've really enjoyed this drive in and have both taken and recommended it to friends. Definitely a great family spot, a good value for a fun experience!
