Well, I just got back last night and we stayed in both Congress Park and the Grandstand on this trip. We had a great view of DD in Congress Park. Room 1425 is a 1-bedroom on the 4th floor and it had an awesome view. Unfortunately we ended up on the 1st floor with a parking lot view at the Grandstand. It was a terrible view. But it was super close to the pool. We kept beer and soda in the frig and just walked back to the room to get drinks instead of using the pool bar.
The picture in my previous post is from a studio numbered 9836. The studio was at the end of the building and not many people used to walk by, it is on the top floor as well
I would plan on a 7-10 minute walk from Congress Park to the restaurants (both Turf Club and Artist's Pallette) and main pool and about 10-15 minutes from Congress Park to DTD.
Congress Park is pretty much in the middle of Community Hall (the center of the resort) and DTD. It is our favorite section of SSR. If you would rather be closer to Community Hall I would suggest staying in the Springs or Grandstand section. The Grandstand pool would be a hit with your four year old.
