Please keep in mind that hours can and do change, so make sure to check back a couple weeks before you vacation to verify hours, and once you arrive, make sure you pick up a Times Guide for the most up-to-date hours and park information. Times Guides can be found upon check-in at your Walt Disney World Resort hotel, or at Guest Relations at any of the parks.
Have a magical vacation!
Amanda
