My current guests have paid for one month of accommodation, and have been called back to their work in another state unexpectedly., only having used about 1.5 weeks. So I would like to make my space available for new bookings after they leave on this Sunday coming up, in hope of getting someone else to pay and I will then offer them a refund. Am I obliged to give the guests a refund for the time they are not using my space due to early departure? Thanks for yoru help, Genevieve
