Hi, John!
You are going to love the reimagined
Disney Springs area. It has turned into quite the destination for shopping, entertainment and my favorite feature, incredible dining options.
While there is bus service available from the theme parks directly to Disney Springs each day beginning at 4pm, there is not direct service from Disney Springs back to the theme parks. However, there is a very easy alternative!
From Disney Springs, take resort hotel bus transportation to Disney's Yacht & Beach Club Resorts. These resorts are located at the International Gateway entrance/exit to Epcot, so it's just an easy walk from their bus stops (Beach Club is the closest option) to this back entrance.
And don't forget to download the My Disney Experience App - there is a "get directions" feature that is super helpful in navigating your way around Walt Disney World® Resort.
I hope this helps, John! Please do not hesitate to reach out to me for any additional questions, or if you'd like my top Disney Springs dining recommendations. I have my favorites and I'd love to help.
Faith
