Hi Diane!
Welcome to the Disney Parks Moms Panel!
Your question makes my heart so happy! I'm so excited to see you planning your
Walt Disney World Resort vacation for May 2021! Fabulous!!
You may book a room-only reservation 499 days in advance and once
vacation packages are released, you can upgrade to a package. You can call 407-560-CHAT (2428) to reserve your room at a non-guaranteed rate. At that time, you can also begin making payments toward your future Walt Disney World Resort vacation. Plus, if you have paid for your vacation in full, or you are almost finished paying and a new offer comes along, you can modify it to take advantage of the offer as long as it is available.
You are clearly trying to maximize every moment you have at Walt Disney World Resort and I love it! Guests staying at a Walt Disney World Resort hotel may begin making
dining reservations 180 days prior to arrival and
FastPass+ selections up to 60 days prior to your arrival.
I couldn't be more excited for you! As I'm sure you have heard,
Star Wars: Galaxy’s Edge, an All-New Land,
Opens August 29, 2019! You will have so much to see and do when you visit Walt Disney World Resort in 2021! It's going to be beyond amazing!
Thank you so much for sharing your question with the Disney Parks Moms Panel! You are so thorough with your planning and I love it! Please let me know if you have any other questions as you plan your magical 2021 Walt Disney World Resort vacation!
