The ADA doesn't work that way.
The ADA definition of disabled is:
A physical or mental impairment that substantially limits one or more major life activities; and has a record of such an impairment.
A physical impairment is defined by the ADA as:
"Any physiological disorder or condition, cosmetic disfigurement, or anatomical loss affecting one or more of the following body systems: neurological, musculoskeletal, special sense organs, respiratory (including speech organs), cardiovascular, reproductive, digestive, genitourinary, hemic and lymphatic, skin, and endocrine."

" Under general rules governing lawsuits brought by the Federal government, the Department of Justice may not sue a party unless negotiations to settle the dispute have failed."
This means that if you are discriminated against, you have no real recourse unless the business or gov't has done it habitually or they choose to fight the definitions of the law.
If the problem cannot be resolved by arbitration, only then a suit can be filed and civil penalties assessed. However, the money doesn't go to the person, it is a civil fine and goes to the Feds. After that process you can hire an attorney and sue the offending party.
In the theoretical world, many things seem impossible. In the real world "shiit happens" and the courts sort it out.
If your physician has documented the need for a wheelchair you are absolutely innocent. However if you are asserting a problem that you cannot document it is a gray area. Gray areas are what get sorted out when your trial begins for cheating. In NV, you will have to prove your case with evidence.
Remember, Gaming Control Enforcement is there to assure the tax base for the State of NV. They make sure the games are legal, but they don't particularly like anyone who is not loosing money. Advantage players and cheats take away from the tax base. While AP is legal it is also a negative thing to Gaming Control since it reduces revenue for the state.
Again, the real world of gambling sucks. All the posturing and theory are academic when you are in the back of a Metro cruiser.
