Hello Kalli, and welcome to the Disney Parks Moms Panel with a great planning question.
I am so excited to hear that you are already in rockstar planning mode for your trip next year.
FastPass+ will save you lots of time waiting in the Standby Lines of some of your favorite rides and attractions. FastPass+ selections can be made by any guest with a valid theme park admission ticket linked to their My Disney Experience account at least 30 days prior to their arrival. For guests staying at select Disney Resort Hotels, with valid theme park admission tickets linked to their My Disney Experience accounts, they can make FastPass+ selections 60 days prior to their check-in date.
You didn’t state if your deposit was for a room only reservation or a part of a
Magic Your Way Vacation Package. If you have a room only reservation, you will need to make sure that you have purchased and linked your
theme park admission tickets to your My Disney Experience account for each person in your travel party. You would be able to pay the balance of your room at check-in. However, If you have put a deposit on a vacation package that includes theme park admission, you will be able to make FastPass+ selections 60 days before your arrival for the entire length of your trip. However, the balance will be due 30 or 45 days before your arrival depending on the terms and conditions of your package. Just make note that your FastPass+ selection window will open at 7:00 a.m. Eastern Time. You will be able to select 3 experiences per day, per person on your reservation at one theme park per day. Good luck with your planning. If you have any more questions before you arrive, please come back and visit us again.
See ya real soon,
Andrea
