Payment plan for Florida resident Disney passes
Jun 25, 2010

Florida residents have a new option when it comes to purchasing their annual passes. Disney will now allow them to use a payment plan for their passes. This option will only be available online for the purchases of a new pass (not renewals) and is not available for residents of other states.

A down payment must be made equal to the price of a non-discounted 1-day Magic Your Way base ticket. Guests will then have 12 recurring payments automatically charged to a credit or debit card.
