Sooooo... some interesting tidbits to report. Expect there to be interactive elements throughout the entire land. Not sure if anything would need to be purchased like HP's wands, (maybe for more effects in addition to this,) but all guests should be able to step on spots, touch things, hit question mark blocks, etc to activate effects.
Not just in the play areas (like the dino roars in Camp Jurassic.) Probably everywhere.
And that's not all. I think they'll be a lot more to do than just the 3 rides in this new land. Universal has learned a lot from the Wizarding World. They know they're gonna have a hit on their hands so it doesn't look like they're holding back.
