Sadly, I am now writing ti you from the Crown Priness..16 day to Hawaii and back to San Francisco. We have had 4 sleepless nights going and now the same returning. Granted, very rocky, but the shaking in the cabins, and 20 seconds of engine straining noises is absolutely ridiculous. It sounds like the ship is in dire need of repair, or there is something major with the stabilizers. It goes off every 20 seconds or so. You CANNOT SLEEP OR REST! Cancel your cruise if you can. There are so many other disappointments..too numerous to mention here. We are done with Princess. You have so CHEAPENED your cruises..and we have been on over 30 cruises with you. You have abandoned your loyal cruisers...we loved Princess for years..
