Answer:
Lisa should implement a differential pricing strategy.
Step-by-step explanation:
A differential pricing strategy is basically selling the same product or service to different customers at different prices.
Lisa will be able to charge a higher price to those willing and able to pay for it, and since the demand for rooms is larger than the supply, a shortage will result. So she will be able to allocate the 500 rooms to those customers who value them the most and are willing and able to pay a higher price for them.
