Lots of people's credit cards -- mainly their Visa's and MasterCard's -- are maxed out. So you've gotta take more than just Visa and MasterCard at camp. Be sure you accept American Express, Discover, and anything else necessary that make things easier for camp families to pay. Advertise everywhere (on your brochure, website, etc.) that you accept all credit cards so your customers and prospects know they've got many options to finance camp tuition.
