There are a couple of threads about people’s reactions to it; from what I’ve seen on other posts and social media, around 20-25% of riders have severe nausea or throw up. And around another 20% have lower levels of nausea. Most of the threads talk about nausea, but not a lot about other issues.
This thread had a poll about motion sickness on Guardians of the Galaxy
It ONLY asked about nausea, not other reactions related to riding. A lot of people added their experiences to the thread and some said they had no nausea, but had vertigo or other issues.
I was in the severe nausea group, but was able (just) to avoid throwing up. I had taken Dramamine before because I was worried about the turning (Omni- action motion). Looking straight ahead helps some people, but didn’t help me because when you are looking straight ahead, your ride vehicle is often traveling sideways.
I felt really bad for about 15 minutes and don’t want to do it again. But, now with some time, I’m glad I did it once (but, once is enough for me).
I don’t ride Expedition Everest or Rock N Roller Coaster, but don’t have a problem with 7 Dwarfs. I can do spinning with no problem on things like Rise of the Resistance, Remy, Toy Story Mania, Runaway Railroad, Dumbo. I had no problems on Harry Potter Forbidden Journey, Smuggler’s Run or Star Tours. I got slightly nauseous after the couple quick up and downs on Slinky Dog.
I can’t do the Teacups - mostly because it turns in more than one direction at a time.
This ride is interesting because some people who normally are not prone to motion sickness got it and others who get it from almost any ride didn’t have any problems. I think it has to do with what individual people have problems with, if they are present in this ride and how they are combined in this ride.
It doesn‘t have:
- drops
- jerking movements
- bumps from going up hill
- extended spinning
- any inversions
It does have:
- a backwards launch
- very smooth motion
- almost constant banking, some of it very steep. Most roller coasters have hills or flat places where you can catch your breath and recover before the next. This one doesn’t
- some sharp turns, often while banking
- the ride car turns sideways to point you at scenes (think Haunted Mansion at high speed)
- darkness
- screens with something going on somewhere most of the time
- banking while your ride car is turned sideways
For me, I think the issues included the almost constant banking, sharp turns and the ride car being sideways while going forward on the track (often while banking.
I agree with
@HopperFan description, especially that it seems like a mouse type roller coaster. The big difference comparing it to that type is the spinning is directed on this compared to random on other mouse types
