Yes, the Spas are 8/6. They are one of the older sections on the resort. I have pics, but they are from 1999, so not sure how relevant it would be to post them here. Vistana is very good with rehab and maintenance as a whole, so maybe someone who has stayed there more recently might have some pics. During our stay in '99, I'd say the villa was pretty nice. Not as modern and fresh as the newer sections. I own in the Fountains, so I did notice a difference----the villa was clean and well maintained, but a little dated. The rooms are larger compared to the newest Cascades.
Like I said, when I stayed in the Spas it was '99 and the decor, while in good condition, seemed to be an 80's style. I'm thinking they MUST have remodeled since '99 though.
