As far as I know, Caribbean Princess is the only ship that shuts down the pools. No matter what anyone tells you, the decision is due to having so many more children and teens on that ship. Our one cruise aboard that ship was the worst we've been on, partly due to uncontrolled and unsupervised teens and children. Fortunately, Princess has taken steps to control the situation, but it will be a cold day in heck before we book another cruise on Caribbean Princess.
I liked the ship, just not much else about the cruise.
