I would've loved for us to WALK through an oversized Hagrid's hut as part of the queue. That would've been so fun! And see more of Hagrid's pumpkins and vegetation and maybe more animatronic creatures scattered around, like his fire blasting newts or whatever they were called in the book, etc. In general, I'd like to see more details around the ride.
And yes, obviously longer. That is the biggest thing I hate about Hippogriff. It looks way too short. It'd Be cool if it was taller and winded around more.
I doubt it'll be different though. Japan, the largest Studios park, got a direct clone. So....*shrug*
