1 Jdalagoadoparaiso Answered How do I cancel a guest reservation? How do I cancel a reservation for a customer? 10 M Adamopoulou Hi! -Jdalagoadoparaiso and welcome to the forum.Firstly, beware of the implications of cancelling a booking, you may have to pay the bill for the entire relocation of the guest. (possibly more expensive accommodation, taxi, etc.) You have to request from the guest to cancel reservation and try to convince him that your property is unfortunatelly unavailable being under emergency maintenance. Of course you also have to inform your BDC local office about the cancellation. Wish you good luck.... 5 Mashi Niwarthana mark as no show..
