Hi Leigh,
As a long-time Seasonal Passholder, I'm happy to be able to answer your question.
Your pass becomes active on the first day you use it at one of the parks. So you can purchase it online and start making payments without worry that you are wasting some of your time. When you buy online, you will receive a voucher that you will take with you to any ticket window at Walt Disney World.
The cast member at the ticket window will verify that each adult is a
Florida resident and issue your official passes, which will expire one year from that date.
We are huge fans of the Florida Resident Seasonal Passes and the monthly payment program. We appreciate the flexibility of hopping among parks and the value of the discounts and benefits you get as a passholder.
I hope you love your passes as much as my family does. Please let me know if I can answer any other questions for you as you begin your year of fun at the Walt Disney World resort. Enjoy!
Wilma
