Here's a map of the Disney Springs Area hotels I created for an old post:
Key:
1. DoubleTree Guest Suites
2. B Resort
3. Holiday Inn Disney Springs
4. Hilton Lake Buena Vista
5. Buena Vista Palace
6. Wyndham Lake Buena Vista
7. Best Western Lake Buena Vista
8. Crossroads Shopping Area (off Disney property)
9. Disney Springs West Side
10. Disney Springs Marketplace
11. Cirque du Soleil Theatre
I mapped the walking distance from the DoubleTree Suites to the Marketplace right in front of the Co-op (#1 to #10). According to Bing, that route is 0.7 miles or 14 minutes. Link to that map:

If those numbers don't mean much to you, here's a comparison. According to Bing, the walking distance between Disney's Contemporary Resort (main building) and Magic Kingdom baggage check area is 0.5 miles or 11 minutes.
