It is winter. You are the manager at Great Wolf Lodge, Niagara, Which is very famous for its indoor water park. You are informed by the water park manager of your hotel that one of their heat systems is out-of-order and they won't be able to maintain a comfortable temperature (i.e. around 30-C) in the water park. The temperature may drop to 20 to 22"C in the park, which many people, especially children, may feel is too cold. It will take around 2 days to repair the heat system. You have around 280 bookings for tonight and tomorrow, and you know the guests come mainly for your indoor water park
