We loved our stay at CSR last year...it was just DH and I. Very quiet, beautiful grounds and landscaping,and loved the rooms and the comfy beds. Restaurants were fine, but the small quick counter service place got very mobbed in the AM. We liked Pepper Market breakfast, but I don't think it is a buffet anymore.
However it is a huge resort...luckily we were in Casitas 4, so just a short walk to get morning coffee. Not sure I would have been as happy if we were at the far end of the resort. For our next trip this June with extended family including small children we are at POFQ, which we think will be a good fit.
