Hi, Cynthia!
The only way to get to Disney Springs from any theme park is to take a bus from a Disney Resort.
So, the most convenient and fastest transportation option would be to exit Epcot between France and the United Kingdom, walk to Disney's Boardwalk Inn or take a ferry. The ferry will drop you off at Disney's Boardwalk Inn, Disney's Yacht Club Resort, Disney's Beach Club Resort and the Swan and Dolphin hotels. From there, you can wait for the Disney Springs bus to take you to your dinner at Boathouse.
Also, you can take a bus from Epcot to one of four
Disney Resorts, both Port Orleans Resorts, Disney's Old Key West Resort, and Disney's Saratoga Springs Resort and Spa. Once you arrive at one of these four resorts, you can take a bus or water ferry to Disney Springs.
Cynthia, enjoy your adventure at Epcot and dinner at Disney Springs.
