In this case the pool is not being blocked for the duration of your stay. Reread the thread. Of course if this would cause you to not want to cruise/stay then you can vote with your wallet. I do believe people should be outspoken when there is a change they disagree with and they should try to enlist other customers to make those statements also - as was does in this thread. On the other hand expecting compensation for every eventuality is unrealistic. If it bothers people so much then yes, they should not use the product, cruise, hotel. But it is hardly actionable requiring compensation
