DH always requests Congress Park. It is the closest walk to DTD, a short walk to the main pool, and has a very nice leisure pool right there. Our room last time was right behind the bus stop.
I'd avoid Carousel, just because it is the most remote and feels that way. If you like that, it's fine. It was just a much longer walk to the main areas.
If you plan to walk to DTD a lot, try for rooms 1101-1436 - they are the closest. We've stayed in building 15 a couple of times and like that location a lot.
I like the upstairs rooms for the balconies. DH likes the patios on the 1st floor (they are open, unlike at OKW). If you get a room facing west, you can see the fireworks at EPCOT!
We LOVE SSR, but we don't mind walking a lot. We used to stay at POR and I felt like I had to walk farther there than at SSR. We walked often to the main pool and Artist's Palette, and I think it took about 5 minutes. The kids loved the slide at the big pool, and DS loved the arcade and community hall. We also walked to DTD often, and enjoyed the walk.
We also LOVE OKW, and I think it feels just as spread-out. Have fun!
