Its my favorite resort! Being so close to DTD is nice in a couple of ways. First all the dining and shopping are a short boat ride or walk away from your room. That also means that if you don't have a car and want to dine at other WDW resorts, you can easily get over to the bus stop area of DTD and get to where you want to be very easily. This resort is also centrally located, you are not far from anything. And we have found the bus service to be excellent during our stays.
SSR has lovely grounds that are so worth exploring and enjoying. It also has the best counter service restaurant on WDW in my opinion. Artist's Palette is such a cut above most other cs places. They have wonderful sandwiches, salads, flatbread pizzas and a very nice little bakery. The main pool is zero entry and has a great slide for older kids and adults and a smaller slide and splash area for younger kids. There is also the newest pool over at the Grand Stand section which has these very fun spray cannon type things and another bar for the adults. Its a short walk from the main pool which is nice. And there are several other quiet pools, all that have hot tubs and laundry rooms (that are free to use) attached to them.
The resort is large however there are shortcut paths all over the place and you can always hop on a bus to take you to another area. When we have stayed there, several times bellmen in a golf cart have told us to hop aboard for a quick ride to the main area. But I actualy enjoy the walk and even when I have stayed at one of the more distant areas have never found a walk to be more than 5-7 minutes to the main area.
I think you will love SSR, its newer rooms/units are so nicely furnished, each one has a lovely view of something (golf course, pool, DTD, open area, fountain, lake) and the cm's are all very nice and accomodating.
