We stayed at SSR in Sept 2010 and I didn't like the resort that much, it just felt too quiet, there was no life to it at all. Almost every time we caught a bus we were the only guests at the stop.
We were in Congress Park in a ground floor room close to the quiet pool. I agree with someone else that it felt dark, a room higher up may have been better. The walk to DTD Marketplace was the best feature of SSR though, from our room we could be at Rainforest Cafe in around 10-15 minutes, I imagine its even quicker now with the extra bridge.
It wasn't too far to the main building for Artists Palette either, but it didn't feel like a nice walk, there was a lot of warehouse style buildings (I think old theatres and similar from when it was Disney Institute) and it just felt like a hot walk along a sidewalk.
Bus service was fine, I don't recall any stupid waits.
In general though, I would rather stay at one of the Port Orleans resorts, they had a nicer atmosphere, more greenery and although the walks around the resort were probably the same length they felt nicer as there was more shade and more people adding to the atmosphere.
However the special offers for UK guests at the time made SSR cheaper than POR once the free dining plan was taken into account and I would only stay again if that was the case again, if I can get POR cheaper (incl dining offer) then that would be my first choice.
and sorry I know you asked about Coronado but I've never stayed, it looks just as bad for being spread out and hot to me!
