If you're in the area and they have availability, it's hard to beat Ghost Ranch for value. RV spots with hookups are $45 a night!
Most guests stay in housing/lodging, so the ranch has a dining hall that serves three meals a day. $16 per person per meal but $30 for three meals on a "meal plan" whe you book, and kids eat for free! All in all we got three meals for our family of 4 and a nights stay while we hiked around trails on the property for less than $100 all in, and the food (upscale summer camp type) was very good.
Georgia O'Keefe lived in the property for a while, so there's a lot of history about her, and there's a small dinosaur and anthropology museum on site.
Chimney Rock hike is not to be missed!
