(a) General.  A public entity that sells tickets on a preassigned basis shall modify its policies, practices, or procedures to ensure that individuals with disabilities can purchase tickets for accessible seating during the same hours, through the same methods of distribution, and in the same types and numbers of ticketing sales outlets as other patrons, unless the modification would fundamentally alter the nature of the ticketing service, program, or activity.
