I saw a 10 year old the other day get on The Vortex with a 2 piece swimsuit and flip flops (no shorts)and nothing was said, but if that ride broke down and they had to evacuate that could be a problem. Keeping patrons safe should be the main thing.
I being a chunky monkey, am thankfull for this topic, I can fit all the rides, I don't know about the WindSeeker. Have been to the park 5 times and yet to see it open.
