A (funny to me) note:
My DH is a civil designer. Everywhere we go, he looks at curbs....driving, walking, riding a bike, whatever. And I hear all the time: "that slope is too much" "curb is too high" "ramp is uneven" etc. He will actually note down the worst offenders and notify the local city office about the out of regulation curbs.
(he doesn't do things like that at buildings though. Guess he feels that architects deserve the lawsuit...
)
Back on track:
DH says that there are both federal and state regulations regarding theme/amusement parks. A designer has to take both into account. He says there are some rides that are just physically impossible for some people to do, due to the nature of the ride. If you can't fit in the harness because your tummy/shoulders/hips are too big, you can't ride. If you're too tall and your head brushes the top of the ride, you don't ride (or if you're too short, and can't fit in the safety gear, you don't ride). If you can't hold yourself upright, you can't ride. It's not discrimination; it's safety.
He sent me a few quick links, didn't have time to dig more. *some of the information may be out of date, but gives a general idea of the requirements.

"There are some situations where it simply is not possible to integrate people with disabilities without fundamentally altering the nature of a program, service, or activity. For example, moving a beach volleyball program into a gymnasium, so a player who uses a wheelchair can participate on a flat surface without sand, would “fundamentally alter” the nature of the game. The ADA does not require changes of this nature."

"In providing goods and services, a public accommodation may not use eligibility requirements that exclude or segregate individuals with disabilities, unless the requirements are
necessary for the operation of the public accommodation.For example, excluding individuals with cerebral palsy from a movie theater or restricting individuals with Down's Syndrome to only certain areas of a restaurant would violate the regulation.Requirements that tend to screen out individuals with disabilities, such as requiring a blind person to produce a driver's license as the sole means of identification for cashing a check, are also prohibited.
Safety requirements may be imposed only if they are necessary for the safe operation of a place of public accommodation. They must be based on actual risks and not on mere speculation, stereotypes, or generalizations about individuals with disabilities.For example, an amusement park may impose height requirements for certain rides when required for safety. Extra charges may not be imposed on individuals with disabilities to cover the costs of measures necessary to ensure nondiscriminatory treatment, such as removing barriers or providing qualified interpreters."

(there's a section in here about curbs..lol)
In section 15, there is a lot of specific information about amusement parks.
