We are at SSR now, and this is our second time in the Paddock area. This worked out good because we go to DTD a lot, and with the walkway closed, if you are in buildings 5,6 in the Paddock area, it is a short walk to DTD.
If you are staying during a busy time of year, I would agree that the Grandstand is great due to first bus stop, and low bus noise due to where the pickup area is. We have only stayed in the Paddock/Congress Park areas and like them both.
