Families who visit these facilities often enough may be able to save money by purchasing a membership. Often, being a member comes with other perks, such as discounts on parking food, merchandise and more.

Another advantage is a little-known benefit called reciprocal privileges. Basically, being a member of certain organizations can get you free or discounted admission at similar facilities around the region—or the country. Generally, you need to present your membership card as well as a photo ID at the partner institution.

We've compiled information on membership and reciprocal privileges for nine of the most popular family attractions in Central Ohio. Note that costs and reciprocity details change frequently, so it's wise to call ahead to verify policies and current details before making a trip. Also included are calculations of the number of visits a family of four (two adults and two school-age children) would need to make to each venue for a family membership to pay off.
