Didn't I hear that Caribbean Princess closes their pools at midnight now? This is just for the Summer season because of the influx of chidren present. (Safety and security reasons) I'm not sure if this affects any of their other ships. One point brought up on another thread, if the pool is open 24 hrs, they do not drain or clean the pool for the entire cruise. Could become an issue towards the end of the cruise, with many children, infants and sun tanners (lotions and oils) taking their toll.
