Back in the early 90's my first two visits to WDW I stayed at the Grosvenor. Every night after Epcot closed I went back to the hotel and walked to DTD. Took about 5 minutes to get to the Marketplace area (now renamed)
Looking back, I can't imagine doing that now - I'm getting a little old!
(edited to add that I have a reputation for being a very speedy walker, but I may not have been as speedy on those evening walks after a long day in the parks)
