So, for background, I originally accepted a 2-week reservation over a month in advance, but I learned shortly afterward that my main job had me scheduled to travel possibly around the beginning of the first week, so I wasn't sure how I'd let my guest in. While I wanted him to originally just accept a modification to arrive at a later date when I knew I would be back in town to avoid (first-time) cancellation issues, we mutually agreed to cancel the reservation so that he could make one reservation.
While I know that first work week of time is still uncertain, I would certainly be available for the weekends in-between, so is there anyway to adjust individual days?
