We didn't care for SSR. Units aren't that big. We were in a two bedroom villa and it seemed rather tight. We were in the Springs building and it still seemed far from everything.
The resort is very big, we felt we needed a car to get around and it seemed very unclear as to what the theme is. I know Saratoga Springs, and horse-racing and natural springs. But, to me that seemed artificially imposed over the earlier fact that it was the golf village and then the Disney Institute. The golf course still makes up a big part of the resort. When we had lunch at the Turf Club, everybody else was coming off the golf course. So, I didn't think it really had much theming.
Add to that the fact that we could see lots of other Kissimee-area and non-Disney buildings from the resort and it had very little ambience for me. Also, for me, seeing Down Town Disney from the resort is like seeing a strip mall from the resort. Does nothing for me.
So, I've never stayed at OKW, but I would pick that one. We have dined at Olivia's occasionally and have enjoyed it.
