Assume that you are a hotelier who has a group booked at your hotel. The group has picked up all of its originally requested rooms and is now requesting additional rooms at the same reduced rates you originally agreed to when their group room’s contract was signed. You do have rooms available to fulfill the group's new request, but you know those remaining rooms could now be sold to the general public at rates much higher than those being paid by the group. What factors would you consider prior to granting, or not granting, this group's request for additional rooms?
