Hello Lori and welcome to the Disney Parks Moms Panel!
Currently, Disney does not offer a payment plan for theme park tickets. However, our family has discovered a way to budget and not have to spend all the money for the tickets at one time. To spread out the cost, we purchase Disney Gift Cards. Not only that, we purchase them at Sam's Club for a discount. It's a win-win! Another possibility is buying the gift cards at Target with their "red card." Once you have collected enough Disney Gift Cards, you can combine them into one at the
Disney Gift Card website, making it possible to order your tickets online. Otherwise, you can call the reservation center, and they can apply multiple Disney Gift Cards to your transaction.
If you have more questions, come on back to the Disney Parks Moms Panel- we love to help!
See ya real soon,
Anne
