If you're a Harry Potter fan near the West Coast, chances are you're pretty excited about the new theme park at Universal Studios in Hollywood.
But if you get motion sickness, you might want to avoid the big ride, Harry Potter and the Forbidden Journey.
Judging by the reactions on Twitter, it seems to be true.
However, this phenomenon doesn't seem to be just on the California ride, as visitors reported motion sickness on the Orlando version of the ride as well.
These could just be a few outliers though, as motion rides do tend to make some theme park attendees sick.
