Star Tours in April 2019. It was a group of 8 of us - 4 adults, 4 kids and at least 50% of us are moderate to severe Star Wars nerds. Highly anticipated FP for the day. A person in the family in front of us threw up on the ride a few minutes into the ride. Oh the stench.
It was like that "Stand By Me" puking scene. Everyone starts gagging. Trying to cover their faces and not hurl. It took a few moments for the ride to stop. And then several minutes for the CMs to rescue us. The longest 5 minutes of my life. The CMs gave us more FPs and the option to ride it again, but only 1 adult and 2 of the kids in our group agreed to get back on. Star Tours has always made me feel a little green and now I just have this terrible aversion.
We've been back to HS 5 times since then, I still can't get up the nerve to get back on that ride.
