Hi Ruth,
I love a stay at
Disney's Old Key West Resort! The theme of the Florida Keys is so lovely, and the boat ride along the Sassagoula River to Downtown Disney is so relaxing.
To find the operating hours for all of the Walt Disney World theme parks for the time of your visit, simply visit the
online Walt Disney World operating hours calendar. Since you mentioned that you arrive on December 5, the link that I provided will take you to the hours for December 5. Using the small calendar icon near the top of the page, you can change the date. This calendar provides information about both regular operating hours and Extra Magic Hours. For example, I see that on December 5, Epcot will offer Extra Magic Hours from 9:30 p.m. to 11:30 p.m. I do suggest that you check the operating hours calendar not only now as you are planning, but also as you get closer to your vacation, as operating hours are subject to change.
I hope that this information is helpful for you, Ruth! Have a wonderful time planning your vacation, and please do not hesitate to ask if you have any further questions.
