Like I said , Expedia often makes changes last minute without any time for a manager to do anything but walk the guest . You don ' t really ' reconcile inventory ' in a hotel . If you ' re overbooked you can ' t just kick people out . Like , sorry , we made too many reservations so we had to cancel yours xoxo . That ' s not how hotels work . Also , suppose that Expedia didn ' t make this change last minute , and somebody did check ahead and notice that they were overbooked . You know what they would have to do ? Walk the guest . They would have to do literally the same thing , the only thing that ' s different is that they would have a little bit more time to find accommodation for the guest . Do you think that hotel rooms just pop up if there are more reservations than there are rooms ?
