We were at Santa Rosa and San Jose earlier this year. We were also lucky enough to make use of the 'cash and points' deal at both. It was hands down the best deal I have ever gotten at a hotel. Both properties are spectacular and the service is unreal.
I preferred Santa Rosa because it is remote and very quiet. We had the largest suite they offer and on two of our three nights, we were completely alone at the Hacienda - which meant we had three swimming pools, a staff of 8, horses, and the kitchen at our disposal. The staff were so good at their job, they managed to make us feel pampered and as if we belonged there (in the village) at the same time.
I liked it so much, I plan to rent the entire Hacienda next spring. Absolutely go if you are able.
