I have a full-blown report in the works, but here's the low-down in short. There are two courses, each devoted to a different drive-in theater/movie genre. The Haunting of Ghostly Greens is horror-driven, while the Invasion of Planet Putt is sci-fi-oriented.
Ghostly Greens takes a spin through a graveyard and other spooky sites, including a pet cemetery. It was the darker of the two sides. Planet Putt sports alien invasion and trippy lighting. The Putt side had a lot more stairs and multilevel challenges.
The cost to play one of the courses is $13.99 ($11.99 for ages 3-9). You can go the double-feature route and play both for $24.99 ($20.99 ages 3-9). You don't have to play the courses back-to-back. Save the receipt for the course not played and you can come back another day.
There's also a 10 percent discount for Florida residents or Universal Orlando annual passholders. (You can't combine those discounts however.)
