I think other wonderful ways of marketing might be the following:
1. Camp Directories/Searches: Adding your camp to campdirectories and other different searchs will allow for parents/campers to find them. I know I have frequently looked through them for camps.
2. Camp Review Sites: There are a variety of different sites that are composed of reviews of each camp. Posting reviews, and having staff or campers, most them would help increase interest.
3. Radio and In-print advertising is great!
