This is more HHN related but this rumor from Screamscape is pretty wild. Grain of salt and all that.
"While two weeks lead-time may be just enough time to slap together a low-quality extra haunt experience in the Fast & Furious queue, that really isn’t how Universal works. Plus remember that Fast & Furious is expected to reopen to daytime guests as an attraction on Sunday morning, November 3rd, which does not give them time to move-out the contents of a real haunt and restore any Fast & Furious content into place in a matter of hours. While some may speculation that perhaps they were just going to use the F&F queue space for a haunt elsewhere, this is also unlikely as the only space that might be made available for a haunt, would be inside the Fast & Furious ride itself. But with F&F reopening the next morning, there isn’t time for this to take place… or is there?
Readers may recall that I’ve also mentioned that Universal Orlando was working up ideas to create another annual festival event, a sort of Universal themed fan-fest to celebrate past Universal attractions and IPs that have been retired, such as Back to the Future, Jaws, Beetlejuice, GhostBusters, etc. Inspired by the “Universal Cool Japan” events that have been extremely popular at the Osaka park, Universal was also looking to create some temporary attraction overlays for their own event in Orlando, that is being eyeballed to fit into weeks between Mardi Gras and the start of the busy Summer season.
One of the rumored attraction overlays concepts that Screamscape was told about would see Universal reprogram the existing Fast & Furious immersive tunnel experience to take on a new temporary Jaws inspired theme. Sure, the guests would still be riding the F&F style party-busses but once in the immersive tunnel, the new projected media and motion-base under the vehicles would easily be able to create a new virtual experience. After all, the exact same technology is already being used over at Islands of Adventure for Skull Island: Reign of Kong. The interesting thing is that if such an idea was used to create a temporary attraction for Halloween Horror Nights here in Orlando, it wouldn’t have to be JAWS themed, they could create any kind of crazy experience they want to tie in with just about any spooky IP concept they can dream up.
