I'm pooh sized, mainly in the hips, and the upper body. I have never had a problem, nor has my mother, who is larger than I. Honestly, the only thing I had a problem with was SPlash, but not because of my size. I have an old injury, and the way I sat down on it popped my hip out, and I was in a bunch of pain. I'm assuming oen of the CM's saw my pain as we were going through and they stopped our "log" for a second, until I adjusted myself and was able to work it back in. As soon as I smiled at the camera and waved, the ride started again. On our way out a CM asked if I was ok, and they were really great about it.
