Does anyone know any Fee-Free alternatives for booking vacation rentals in Davenport FL and in general?
Be sure you're informed about the new VRBO Traveler Fee, implemented in Feb. 2016. It ranges up to 10% and is added to your rental cost. It is paid to HomeAway/VRBO, the owner can't waive the charge unless you book directly with the owner.
A good source of information on this fee (and others) plus your alternatives for avoiding the service fee (how to find and book with the VR owner directly):
There are still fee free listing site options, a newer one for vacation rentals that is starting to get traction is HomeEscape, https://www.homeescape.com/ (free for guests and owners)... for now.
