I have an upcoming trip and am worried about fitting on rides. I know there are test seats but was hoping to get an idea from people who have fit prior to going so I'm not as crushingly disappointed if the test seats don't work. I've ridden all the rides comfortably in the past but have now gained 20-30 pounds or so from my last visit. I'm roughly 5'8, 270 pounds. I did my best to measure and think I have a 45" waist, 54" hips (though I don't know if measuring myself with the tape is 100% accurate). Has anyone had any experience riding at this size?
