Title III of the ADA sets forth the following general rule against discrimination in places of public accommodation:

No individual shall be discriminated against on the basis of disability in the full and equal enjoyment of the goods, services, facilities, privileges, advantages, or accommodations of any place of public accommodation by any person who owns, leases (or leases to), or operates a place of public accommodation.

42 U.S.C. §  12182 (a) (emphasis added).

The definitional section of the statute specifically identifies twelve (12) particularized categories of "public accommodation." 42 U.S.C. §  12181(7) provides:
