I'm leaving for WDW is 4 weeks and I've managed to lose 35lbs but I'm still 275, 5'7, and carry most of my weight is hips, butt, and thighs. I see here alot of heavier people have almost no problems with the rides but from what I see, the majority of people carry their weight in their bellies. Since my hips are 60 inches around I'm stressing big time that I won't fit in the actual seat. Especially RnR and EE. In yalls opinion will I fit? If it helps, I just flew southwest and fit in the airplane seat and did not need a belt extension (barely). TIA!!
