We stayed there last summer, as part of our first
DVC stay, and it was a lovely resort. I liked that it was small and compact, compared to BWV.
My DD 13 really enjoyed the springs pool and it was never too crowded, even though we were there in August. We had a rental car so I don't know how the bus service was, but it was great taking the boat to/from MK. Every time we went out to go, the boat was just arriving and it was an easy ride. In the AM, the boat they use is bigger so they can take more people if you are wanting to go for rope drop.
The walk from the villas to Roaring Forks (CS) or the merchantile was very easy. I didn't think the rooms were that bad, but I can see that having a few updates would be nice (ie: flat screen TV).
We thought the space in the studio was the biggest of the three we stayed in with BWV being 2nd, and BLT being the smallest.
I loved, even in summer, sitting in front of the fireplace, in the rocking chair, reading a book one night (the AC was on so not too hot!!) in the common area. It was just a very serence resort!
Good luck!
