USF needs attention BAD, and clearly with all the retro merch out and the popularity of it a classic property making a comeback would be an excellent addition to the park. Now if I wanted to go to easy route, I would say build a Back to the Future roller coaster that could become something like USF's Velocicoaster, a high thrill attraction that will draw in guests regardless of connection to the movies. 88 mph launch anyone?
If we want to get ambitious though and not stick to just one property, I think there's a great ride concept somewhere. Use the Scoop ride vehicle to take us on a trip through Universal Studios Florida...in 1990. Doc Brown has just rented out a soundstage in production central, and has invited Studio guests to star in a film showcasing his newest time machine. We board and drive through the soundstage a bit before blasting off into the past and finding ourselves in a slightly different park. Through some mishaps we break into soundstages of old attractions. An animatronic Kong chases us down city streets ala the Indominus Rex from Beijing's Jurassic World ride, we drop into a lagoon as Jaws tries to take a bite out of the ride vehicle, and we dodge debris in subway station earthquake. Flying above the park finally we take off and go back to the future watching the park change into how it is today before our very eyes, and then immediately crashing back through a soundstage wall to the unloading area. Yes it's a super stretch but could be a great tribute to the rides and movies that were once present in the park.
Totally wasn't inspired from this video.
