Dynamic pricing is quite commonly adopted

I asked the front desk staff in the hotel in Korea for the room rate that was charged to me.

She said that the rate varies every day.

So, the hotels use dynamic pricing, like airlines and taxis. It has now become a norm.

The staff could not tell me the rate that I have paid, because they sell the room to the travel agent at a special rate and the agent marked it up to cover their expenses and profit.
