Of the areas we've stayed in at SSR, the most close-but far-away in feeling was the new Grandstand section. It's close to the CH, the boat launch, the bus stop, the spa and the restaurants.
The Springs is also close to the main building (CH,etc), but it doesn't feel as distant as the Grandstand.
Congress park and the Paddocks would be closer to DTD, but further from the main areas, and the Carousel seems to be the furthest from everything.
Good luck in getting a great location!
