A sell$-$through room availability strategy is especially effective when:

A$.$ the number of check$-$ins on a particular day is expected to strain front office resources.

B$.$ a peak in occupancy on one day may otherwise adversely affect reservations on either side of the peak day.

C$.$ the hotel is expected to be near full occupancy for several consecutive days.

D$.$ the hotel is not expected to achieve its optimum sales mix.
