During its 12th annual event, Gay Days at Disneyland expects to attract more than 30,000 LGBT visitors from across the U.S. to Disney’s famous theme park in Anaheim, Calif.

The unofficial event — neither publicly sanctioned nor supported by the Walt Disney Co. — is scheduled for Oct. 2-4.

Gay Days Anaheim is a “mix-in” with the park’s other weekend guests, but gays and lesbians are encouraged to wear red shirts in order to identify each other and to show strong numbers.
