You can also walk to DTD though the golf course. Walk down to the golf course and follow the path. You go over the river, across the parking lot, and end up over by Cirque de Solei.
At night they put a security guard on the path to watch over the people going back to SSR. Also to direct people who were having too much fun at the Adventurer's Club (Not that I would know anything about that)
I prefer the Grandstands. They are close to the boat launch / path to DTD (they are in the same spot) They are pretty close to the main building (food court/check in/main pool) They are the only "group" of buildings that have a bar at the quiet pool area. Even if you don't drink, it's nice to be able to grab a soda or something. All the other "groups" of buildings have a quite pool (or share one) but you have to walk all the way over to the main building if you want something to drink.
Some also have a nice view of the golf course, if thats your cup of tee. thats like a joke, tea, tee, golf, ... yeah, its late.
