Hi, David!
This is a great question!
Your Premium Annual Pass is a great way for Guests to gain unlimited access to all of the magic at Walt Disney World; the four theme parks, two water parks, DisneyQuest, ESPN Wide World of Sports and Disney's Oak Trail Golf Course are all part of your current Premium Annual Pass to WDW.
The Disney Premier Passport, however, gives the Passholder all of this plus unlimited access to Disneyland Park and Disney California Adventure Park, both in California. This is a great opportunity for those families who might like to visit both CA and FL parks to be able to do so with the ease of one convenient and money-saving Annual Pass.
For more information about the
Disney Premier Passport, take a look at this link, where you'll find more specific information.
Happy shopping! Send more questions as you think of them, David. I'd love to help!
