Most of the rides are simulators, which I don't care for.
So of the non-simulator rides (because I can't do many of them either) this is what I ride and my tolerance for thrill is much lower than my husband
HP rides:
Hagrid's although that was a one and done for me due to my personal level of intensity
Flight of the Hippogriff and my husband and I laugh the whole time (partially because he's so tall lol)
Non-HP rides between both parks:
Jurassic Park River Adventure
Dudley Do Right's Ripsaw Falls
Popeye and Bluto's Bilge-rat Barges
MIB
E.T.
Cat in the Hat
Suess High in the Sky
Mummy- I can do just haven't in a while and it wasn't open due to refurbishment last May when we went.
My husband can then add:
Hulk
Hollywood Rip Ride Rocket
VeliociCoaster
Dr Doom's Fearfall
Those are the non-simulator attractions we do. That's not all the non-simulator attractions available just the ones we do.
I absolutely agree that USO had a tendency to build attractions with simulators BUT that doesn't mean there aren't options without them. Storm Force for example isn't simulator but not an attraction we're personally interested in going in. For the OP this is where going to the website is going to help them.
We did two days in the parks. I felt it was overkill.
That makes me think it was more about just rides and only rides for you which no biggie but def. more than that to the parks.
Going through the nooks and crannies of Diagon Alley for instance takes some time. So does watching the shows in the HP areas and outside the parks.
We stopped for example to watch this show for a bit (screenshot of the video taken):
While it's now shuttered (and hopefully they are coming up with something else) there was the nighttime water, light, firework show over on the Studios side. HP has a nighttime castle show. We aren't parade people but they did have one going on (I think that one was shuttered though).
Going with EP is going to mean that you're probably getting through the attractions fast but that should allow for time to soak in the rest of the parks and even after going to USO enough I still find things to do and I know I'm missing things as well. One thing to note is that USO is in the process of replacing attractions over by E.T. and Lost Continent is finally closing so Poseidon's Fury walk through attraction (which has lights, projections and minor fire stuff but is not a simulator) is closing as well. But new things will be coming
