@Shannon579 I have to gently ask why you would spend any additional time or money on this. Or even thought.
As hosts we all get guests who challenge us from time to time. You don't have a lot of reviews, but these two have you suspicious. I don't know if there is any reason for that or not. But let's just say there is. Here is the solution: don't use instant book. Vet your guests. Ask questions until you feel comfortable with them and then allow them to book. Let this go. Guests read this forum as well. If they see that a host is threatening a lawsuit for a review, you have really ruined future chances of booking, snakes, mothballs and crinkly plastic notwithstanding.
Please don't take this the wrong way as everyone is trying to help you. But in order to be a successful host, you have to give up some control. You have to make concessions. You have to expect that some people won't be great. You have to expect to hear some feedback you don't like or that surprises you. I know you are tying your cost to value and expectations but your guests won't. They will all want different things. As the saying goes, you can't please everyone.
Let this one go. You have gotten some really good advice here. Take it onboard and save your attorney money for something else.
