We took the DS bus on the 2nd day of the new bus loop stops. If you are at a WDW hotel get a DS map by the front desk to get your bearings once you get there. You will be dropped of near the new Town Center and have to walk to the older Marketplace section. 5 minutes or so at a brisk walk, more likely 10 minutes if you want to take it slow to get to Raglan Road.
The new dedicated bus lane on the road leading out of DS makes the return trip a lot faster than in the past!
