Hi, Eletha!
Hakuna Matata! No worries! To get to
Epcot from
Disney's Animal Kingdom, simply
hop on a bus. Bus stops are clearly marked with their destination, so find your bus stop and a friendly driver will zoom you over to Epcot. You will be dropped off at Epcot at the Main Entrance near Future World.
You even have another option. You can take the bus from Disney's Animal Kingdom to
Disney's Beach Club Resort. From there, take the lovely stroll to the International Gateway Entrance of Epcot (less than 10 minute walk). If you are dining in one of the countries, this might be a better option as when you enter through the International Gateway, you will be entering in between England and France, right in the heart of World Showcase!
With either option, plan to be at your bus stop 60 - 75 minutes prior to your dining reservation. Buses run approximately every 20 minutes, but you are traveling during a very busy time so I don't want you to feel rushed if you need to wait a bit for the bus or if lines are long getting through security.
Enjoy your visit to Walt Disney World, and wishing you a very happy
holiday visit!
