18. First, book your vacation package.
As soon as you and your family have decided that a trip to Disney World is in your future, set your trip dates and call an authorized Disney vacation planner as soon as possible to get the best rates for your stay at a Walt Disney World Resort hotel. A vacation package is your best bet because it bundles your resort hotel stay with your theme park tickets and even your Disney dining package if you choose to add that to your vacation. You can book your resort hotel stay up to 499 days in advance—Disney World encourages you to plan early!
