While volunteering at the Zoo always earns points toward a free new or renewing membership, working Ghouls at Grassmere is twice as nice. Each Ghouls event volunteer hour counts as two, earning a membership - at the Family level or below - in as little as 25 hours.

Hours accrued by family members may be combined to reach the total. So you could break it up over the course of the event, with Dad, little Johnny and Jason volunteering on Friday (15 hrs), Mom and Betty Sue on Saturday (10 hrs) and voila, free membership. Or bring the entire family out to volunteer on one evening to accomplish the same goal. With nine event nights there are plenty of shifts to go around.
