Hey, I'm a big guy myself at one point <315 and I visited SFMM. My advice, stay away from OTS rides, those were the most problem givers. However, they also do have larger seats with the double buckle for bigger guest including batman, scream and superman, haven't tried riddler though when I went, was denied lol. As far as leg room on like goldrush, crossed legs works fine. Only time I've been in pain was on revolution, my knees were crushed by this metal bar on the back of the seat (not lap bar). Most.Uncomfortable.Ride.Ever. So to anyone with size as a problem, just ask the dispatcher or whoever is directing you to seats, that you'd like to find the bigger seat and they should accommodate quickly.
Thanks to you and the other posters who have replied to my post. What is an OTS ride?
Given what I've read and what I remember, I will be avoiding Riddler and Batman, and Gold Rusher - none super losses. I remember being able to make X2 happen, so hopefully I can still pull that off. Green Lantern wasn't there last I was there and I'm feeling like my friend my want to try it - I will try to see, based on time, and wait, if I get in line and only he fits - so be it. And I had to look up what YOLOCoaster meant. I'm eager to try it myself, so hopefully the padding on it isn't too much.
Thanks everyone for your help!
