Discussion the question on one page

Today, hotels use their knowlege of guest behaviors to adjust pricing to provide “the right room to the right guest at the right time at the right price”. What this means is that there are typically a wide variety of prices charged to various guests staying in the hotel on the same night. Assuming there are no differences in the room itself (and in most cases, there are not) do you think it is ethical to do this? Whether you choose yes or no, defend your position. And do not, under any circumstances, use the word “fair” or “fairness” – or the concepts of either – in your answer.
