I've attended the (week long) Texas Star Party at Prude Ranch for many springs. I've never camped, but have always stayed in a bunkhouse.
It's a fun place - They have horseback riding, a nice dining hall, basketball, tennis, hiking, etc. And, as has been said, you won't find a better part of Texas to spend a few years.
