Back from the trip on the 4th of July and since you asked to know how it went, I will give you the rundown (and this may be helpful to other large people considering a trip to Hershey). For reference, I am 6'2", about 275 and generally proportionate [i.e. I don't carry all of my weight in any one place
]
Skyrush - I fit fine - very comfortable seat for larger riders as it is wide and flat.
Great Bear - I fit fine in the special seat for fat people, although painful on the hips as those B&M invert seats come up high on the hips and you have to ram yourself down in there to fit - same as Alpengeist. Painful hips for days since I rode this 3 times.
Comet - fit fine, no problems
SooperDooperLooper - fit fine, no problems
Trailblazer - fit fine, no problems
Storm Runner - fit fine, no problems (probably my favorite ride in the park, by the way, and very short lines all day since it is tucked in the back and with everyone at Skyrush and Fahrenheit)
Fahrenheit - fit fine, although a close call on the seat belt reaching
Wildcat - fit fine, no problems
Lightning Racer - fit fine, no problems (quite possibly the best ride in the park - now I know what people are always talking about)
Did not ride Roller Soaker, Sidewinder or Wild Mouse due to lack of interest. Won't bore you all with the rest of the details, but overall a fantastic trip and was glad to find the coasters so forgiving for larger folks.
