Even one enrollment can make you smile but wouldn’t you rather sign up a BUNCH of kids at once? What if you went to your mailbox and found one envelope containing 50 (or more) camp registrations?
One very effective way you can reach many prospects at once is by targeting groups, clubs, organizations and associations and offering a discount to their members. In most cases the Executive Director (or whomever’s in charge) will forward your offer to their membership, not only because it makes them organization look good, but also because a summer camp discount is a nice membership benefit any way you look at it.
