With these rules in place, Sarah quickly sees an increase in revenue, with pricing that reacts automatically with supply and demand. So when a massive snowstorm rolls in, and skiers and snowboarders are taking off work to hit the slopes over a long weekend, Sarah's lodges are priced appropriately for the high demand. The busier they are, and the closer to the stay date it is, the higher the prices.
Sarah might even consider adding a rule that lowers the rates when occupancy is below a certain percentage if she thought she could attract more business that way. The great thing about yield management is you can try out a rule for set period of time and measure your results to see if it was effective or not.
