My answer is you need to be one step ahead of them and that comes through experience. I just joined but if it happens to me they will pay based on my settings that I am allowed to use. I have a moderate cancellation policy in place but there is a strict cancellation policy that can be used as well. Go into all your settings and set them to benefit you and not the guests since you are the one who stand to loose. Every time I get burned, I learn a lesson and use that lesson against them so it will not happen again. I leave very little wiggle room for them to use my time and money.
