Here is another one that is free
www.pickmyvacationrental.com -- you can add 1 image, descriptive information, as well as a link to you listing on another vacation rental by owner website. We are adding unique travel guides for each new location in the United States we are trying to cover. Our goal is for vacation rental owners to benefit from more exposure through our site, but still direct renters to the tools they pay for on the sites that offer. The intent is to keep scheduling and direct renters to a central location, while expanding your reach over the internet. It is a win-win for everyone, since statistics show that vacation home owners should advertise their rental on at least 3 websites to receive the most beneficial exposure.
