We've stayed at Congress Park, Paddock, and The Springs on our last three visits. People on here who are a lot more knowledgeable than me about SSR room placements can tell me if I'm wrong, but if I had my choice for a standard studio based on where I've stayed previously (we've only stayed in 1 or 2-bedrooms), it would be firstly Congress Park and then The Springs. I have not stayed at the Grandstand, but it looks really nice. For us, it's that we prefer to be closer to Disney Springs so we can walk over there in 5 minutes. I don't think you can go wrong with wherever you stay, but I'm very biased to this resort.
