Here is the problem with giving a discount to a hotel that is already selling lots of rooms.
You have a hotel at 75% occupancy selling rooms for $100.
You give 30% off, now room are selling for $70 but occupancy is %100.
.75(% sold) * 100(price) *100 (rooms) = 7,500
1.00(%sold) * 70(price) *100 (rooms) = 7,000
Picture doesn't get better when 5 for 3 is actully a price of 60. And a real world occupancy % is not 100.
So having people come to the parks for 3 days instead of 5 causes Disney to lose money? I don't get it?
