That's not where this ride is having problems. Ursula sized I can see being an issue but I don't think it's going to be wide spread problems. what is causing the most problems is large shoe size and taller legs.. it just doesn't let your legs go into place and that dominoes to your back much to far out.
I did get locked in fine, I wasn't squished at all in the ride. there was some important body parts that were not happy with the situation and the seat that I dont' think anyone would call comfortable.
EDIT: I didn't mention that I almost didnt' get locked in and it was my height with compounded where my legs fell partially because of size but it wasn't my torso that was the issue or my calves, it was that there wasn't enough room for my feet to be further in.
