Hi I had a problem where I had a new booking that I accepted, but a couple of hours after the booking, my current guests contacted me and asked to extend their stay. The job they are doing will last quite a bit longer. So I contacted the later new booking, told them the situation about my guests needing to stay longer if possible and offered to reschedule a bit later with a free day if they were interested. They instead offered that it was no problem and that they would cancel the booking, so my guests can extend.
I feel like I am in trouble. Where did I go wrong, and what should I do?
