Just a thought:
I recently stumbled upon a site of a startup consulting company (looks very new) that is trying something that, to my knowledge, is a new strategy. Instead of paying for listings on trip advisor or simmilar sites, they will manage (on commision only) listings on all of the relatively new and hight traffic so called "reservations 2.0" sites like airbnb. I inquired and was fairly impressed. In the past I've been somewhat skeptical about these sorts of sites - but the risk seems very low, and those sites do seem to be gaining a fair amount of traction. The website was
groundbnb.webs.com. I would love to know what you or anyone else thinks about it.
