Why are you putting a drag on your business with the fixed price list?
You're losing revenue
Pricing with fixed prices ignores unexpected spikes in demand and forces you to sell at a lower price than people are willing to spend. It basically causes you to lose money.
You're left with empty rooms
When demand drops unexpectedly, the static price list leads you to not adjust prices, and you fail to sell rooms. You are left with an empty facility when you could be getting minimal occupancy instead.
You ignore what is happening around you
How much do travelers spend in your destination? How does the demand for rooms change throughout the year? With a fixed price list that prevents you from "testing" the market, you will always be unaware of these changes.
Are these really the most profitable prices?
We know what you're thinking: even with the fixed price list, you propose special offers that allow you to vary your prices. But who assures you that they are the most profitable ones? If your prices are fixed at the outset, you will always be left in doubt.
