Hi Bridget! Thank you for bringing your question to the Disney Parks Moms Panel.
Some of the great perks that come with
Walt Disney World Annual Passes (besides an entire year of magic!) are
discounts on dining, merchandise, tours and recreation, as well as
exclusive Special Offers just for Annual Passholders.
Currently, there is a limited-time
Bring-a-Friend offer for a 1-day ticket with Park Hopper Option. While special offers change frequently and I do recommend checking back, to be honest I cannot recall an offer for Annual Pass discounts on multi-day tickets being offered in recent years.
There are occasionally ticket offers available to the general public, such as the
Summer One World Ticket.
Don't forget, if you are visiting with family and friends, they can benefit from your Annual Pass in other ways besides discounts on tickets. Annual Passholders are eligible for complimentary Theme Park parking, Disney PhotoPass downloads, and many discounts are valid for the Passholder and up to 3 guests.
I hope that helps! Please visit the Moms Panel again if you have any additional questions.
Anne Marie
