We were one of those lucky families that got a PIN code in 2009 that upgraded us from ASMusic to SSR 1 bedroom villa with FD. I'm not sure I will ever be able to stay anywhere else...we are totally spoiled now! And unfortunately, SSR is way out of our price range so I doubt we will ever be able to stay there again.
The resort is rather large...we stayed in the Carousel area and ended up driving to the pool. However, we were close to the bus stop and the kids loved the pool...I think they've upgraded that pool in the past year. I also enjoyed the peacefulness of the resort. I can't say anything about the studios, but the 1 bedrooms are beautiful and the washer/dryer were very nice to have...I stuck a load in every morning and Disney Magic moved it into the dryer every day so the clothes were clean and dry by the time we got back at night.
