Sometimes we get so consumed marketing our camps the traditional way (website, blog, print advertising, etc.) we overlook our absolute best marketing strategy: hiring superb camp counselors and staff.
Skilled camp counselors know how to connect with kids like no other marketing tool I know. Sure, you can get a kid to sign up for camp the traditional way. But your counselors, man, they're the difference makers. A good camp counselor who your campers look up to can be responsible for keeping the same kids at camp year after. And that means high camper retention rates, lower marketing costs, and phenomenal word of mouth referrals.
I don't know if there's any such thing as marketing magic, but if there is, your staff might be the ones who create it.
