I agree. What about kids? They won't fit in the seats if they are all made to large size. I can't sit in the large seats as I am very thin. There has to be a limit and there are likely weight limits for a coaster. There are also health risks involved, so sorry, they can't accomodate everyone!
Exactly...think about it- these rides typically have a 48 inch or 52 inch height restriction. My cousin is 8yo, entering 3rd grade, 50 inches and fits into a size 8 childrens. She is a tiny person- as most 8yos are-she's just a little kid.
YET- she is allowed to ride HUGE coasters. Meanwhile- someone who is a size 14 womens, even a size 20 womens, over 200lbs, and is 70 inches tall can also ride in the SAME seats. I'm a size 10 women's and 5'8 and I think it's a real feat that they can make a coaster that safely fits both she and I in the same seat/restraint.
The reality is that they have to make these rides fit a 60lb 8yo and fit a 200lb woman- that's a huge task. Asking for these rides to carry that same 60lb child and a 270lb man- that's nearing impossible.
It's about safety and they have to make a ride that fits perhaps 80% of the population. That's just the way it is.
