As an Alum, I can buy a pass for $156/month ($78/each) to use all Stanford Sports facilities - Pool, AOERC, ACSR Fitness Cente, Gyms, Redwood city facility, all fitness classes, etc.
This is something allowed, nothing wrong: the plus one can be a partner, roommate, friend, sibiling, aquitance, etc.
Message me here if you're interested to enroll and share a Membership.
