What I am saying is that it is cheaper to purchase a Family Priority membership, even if only one plays the championship courses and the other plays only the executive course, AND uses the priority pools.
The Familiy priority membership pays the executive trail fees and priority pool fees for both members of the family.
I know this because my wife only plays executive courses, and also uses the Hot Tubs at Glenview and Hacienda. And it is cheaper for me to purchase a FAMILY priority membership which covers everything. Otherwise I would have to pay for priority membersship for me, trail fees for my wife, as well as paying for priority pool membership, which is more than a family priority membership.
