I have a guest that has a 7 day reservation. He just requested to change the arrival date and end date, also adding an additional day. The days he has requested are at a higher nightly rate since it is now over the 4th of July. But the request shows that the original payout and the new payout are exactly the same..how can that be, he added one additional night and booked 3 of the nights at a higher rate...what should I do?
