Back when we were just using camping to drive traffic (our parties were weekly instead of every day at the time) we were reliably getting 16,000 traffic from one 4-slot camper.
The Bonus Camper is designed to make your camping area a fun active area. Campers earn extra by chatting, and the various configuration options make it so that attentive campers earn more money!
In addition, an anti-zombie feature will require campers to speak every so often or they will stop being paid. Now that the client is open source, alts and zombies abound in the world of camping - no reason not to try to get their traffic without paying them, right?
Actual testimonial from Candyland campers:
Vidd Barbosa: I like the fact you can move around and do things while camping!

Persephone Loon: The chat bonuses encourage community building
Persephone Loon: It's great to be rewarded for being sociable!
(later)
Persephone Loon: Having a queue means knowing you WILL get a spot, eventually.
