Hello Deborah! Welcome to the Disney Parks Moms Panel.
Celebrating Thanksgiving with a fine dining experience at Walt Disney World Resort sounds like a magical meal. My wife and I have Advanced Dining Reservations for
Chefs De France but alas, we must wait until we visit in January 2019 for the
Walt Disney World Marathon Weekend.
As far as your travel plans are concerned, I think you have planned the most expedient route using
Disney Resort Transportation. By taking only one bus to Disney's Beach Club Resort and using the International Gateway entrance for Epcot, you have the shortest distance to walk, especially with the France Pavilion right next to International Gateway.
I recently recommended a similar route for Guests experiencing
Bibbidi Bobbidi Boutique at Disney Springs and traveling to Epcot for
Princess Storybook Dining at Akershus Royal Banquet Hall and the Norway Pavillion is a much longer trek from International Gateway then Chef De France.
The only quicker route would be to utilize the
Minnie Van Service or arrange your own transportation to Disney's Beach Club Resort, albeit that comes with the added cost that the complimentary Disney Resort Transportation does not require.
Bon Appétit!
