We did the Hollywood Drive-In mini golf a couple of weeks ago and had a great time! We did it at night, that's when I would recommend to go, the lighting and effects are really cool. There are two courses to pick from, a Sci-Fi theme and a Haunted theme. We did the Haunted theme and loved it, and glad we chose it, it looked a little more fun than the Sci-Fi theme. You need to pick the side you want when you pay.
There is one adult allowed to get in free with kids in each party, otherwise everyone in your party has to pay whether you play or not.
It certainly wasn't cheap, but great entertainment for a night out. We thought it was worth doing, knowing the cost of the night out would be expensive. Think of it as a "theme park" miniature golf experience.
(PS...we love Disney's mini golf, but this one at night anyway, way surpasses them!)
Have fun!
