We just returned from a SSR visit with a room in Congress Park. We loved the rooms - by far the most elegant we have seen at Disney. Our one-bedroom was very well laid out.
If night time views are a priority for you - Congress Park is beautiful.
For closer access to the main pool, arcade, etc. I would choose The Springs. With older kids or teens who might be hopping over to use those facilities on their own, I would prefer that area. SSR is pretty spread out & busses seem less frequent than at OKW for hopping up to the main areas.
During our visit, the model units were located in our Congress Park building. Very busy & definitely placed a premium on parking. With our ground floor patio, I sort of felt like we were on display. I assume this will get better after the resort sales slow down.
Overall, I think any area of SSR will be great. They are doing a great job of using the spaces between buildings - lots of fountains and water features. For daytime relaxation, some of these will be prettier than the Congress Park view. For an afternoon rest & swim kind of family there will be lots of pretty balcony views in all areas; night owls will enjoy the DTD views in the evenings.
Be aware that the fireworks are LOUD from Congress Park, but by the time you wake up & hop out of bed to look at them - the show's over!
Hope this has convinced enough of you to stay away from this nigt owl's Congress Park room!
