Hi there, Sarah!
It's always a great decision at one of the Walt Disney World Resort hotels when you are in for a visit, The level of theming and attention to detail, the service you'll receive, and the extra perks and amenities all come together to make a Disney stay a great experience.
Disney transportation begins running one hour earlier than a scheduled Park opening. Fr example, if on one day, Epcot was slated to open at 9:00 AM, and the Magic Kingdom had its opening scheduled for 8:00 AM, you'd be able to catch your bus to Epcot at 8:00 AM, and your Magic Kingdom bus starting at 7:00 AM.
When you check in, you will be provided with Times Guides for the dates of your visit so you can plan accordingly.
Extra Magic Hours, of course, are factored into Disney transport planning. When you are ready to take advantage of these extended hours - either morning or night - please make sure that every member of your traveling party has a valid Key to the World on hand to ensure admission. This confirms that you are Guests at a Disney Resort, and are entitled to this fun benefit.
Have a wonderful trip!
See you later, celebrator,
