Like, honestly, there's no way Universal could go wrong with that! Knotts was able to completely update two of their classic rides with new figures and effects and they've both been huge hits and lots of guests visited just for that. Same thing with Disney, their recent large upgrades have been very well received.
Like, if Universal was able to have a massive campaign 10 years ago for "Now Wetter Than Ever!", they can have an even cooler and bigger marketing campaign advertising a completely updated River Adventure that's "Now More Real Than Ever! If you think Jurassic World was a monster of a movie, it's nothing compared to the newly updated Jurassic Park River Adventure! You'll wish it was just a movie!"
Update the animatronics to be super realistic, add a few new props/new animatronics and projection mapped effects that subtly tie it into Jurassic World, and...bingo! Dino DNA!
Like, with them advertising the ride more right now, it's especially embarrassing when the guests see it in person.
