I'll be honest, a 60 day no refund policy sounds insane. If you're able to get people to book with you, great for you, but I can't see a world where I ever would sign up for that...
Also, if they do cancel in the 60 day window we relist the dates and if they get rebooked then we give that money to the person who canceled.
Sounds like the marker is working as designed. Buyer and seller have to find agreeable terms, otherwise no deal and move on
