If you have a property you own or manage and would like to derive extra income as a vacation rental, then VRBO should be your first choice. Their customer service is decent, their pricing is fair, the market exposure is good and their interface is good. The best part is that VRBO gives you many choices for important parameters such as cancellation policy, refund policy, booking contract (you can write your own). I could go on and on. Suffice it to say, if it wasn't for VRBO, I would simply sell my properties.
