It is pretty OK for overweight people.The seats are pretty large, and you each get your own bar.  Entrance and exit aren't bad at all. I also am seeing people looking for the incredicoaster weight limit -- and as far as I can tell, there is none.  I think that most guests will feel comfortable, but it is tight if you need a lot of room on either side of you -- much like any seating (airplanes) would be.
