@Justine336 We had someone book, then want to change dates due to elderly mothers surger, then they ended up canceling anyway.
2 options-
tell them to cancel and they will be refunded based on your cancellation policy.
since they haven’t checked in yet, just tell them to cancel and you will authorize full refund. This is what I do. If they want to rebook later on they will since there won’t be any hard feelings if you give them full refund.
