Currently Annual Passholders at Disneyland do get benefits including on merchandise, food and parking. Currently though they do not get a discount on tickets.
Hereof, does a Disney annual pass work at all parks?
With this pass, you get: access to all four theme parks (Magic Kingdom, Disney Hollywood Studios, Epcot, and Disney’s Animal Kingdom), with park hopping, most days of the year with most holidays blocked out (calendar here), subject to reservation requirement.
Simply so, is Disneyland still free on your birthday?
The Disneyland Resort did give a free park admission ticket to Guests on their birthday as part of a limited-time promotion several years ago, but this is not currently offered. Tickets to enter Disneyland Park and Disney California Adventure Park must be purchased for all visitors ages 3 and up.
