I have a guest arriving in 2 days and have moderate cancelation policy, so no refund within 5 days of reservation. He wants to reduce his stay from 2 nights to 1 night, with one night being the first night of a holiday weekend. My property does not book well last minute so if I let him alter his reservation, I will be out one night of income. I am considering sending him an alteration request to alter the dates of his stay by one night and giving him a 50% refund for the cancelled night as a customer service measure. I am looking to other hosts for opinions or similar experiences as insight as to what I should do.
