Parallaxe

Update: it got so bad that I had to call guest services around midnight. Staff was awesome and gave me a vacant inside cabin for a good night's sleep. They also told me that it's a known issue with the anchors on the Prima: swell/waves and the ship's movements seem to let the anchor bang against other ship's components, leading to this infernal noise. So I suppose all front facing suites like mine could be affected, if swell/waves are at a certain strength. Hope it helps.

Avoid cabin 10100 at all costs! I'm currently on Prima's transatlantic cruise from Barcelona to New York and whenever there's a bit of swell the noise in this cabin is infernal. Almost every minute it sounds as if we were hitting an iceberg or running over another ship. The banging and crashing sound is unbelievable. You can even feel the impact. I have no idea what that is - sounds almost like a loose anchor swinging around and hitting against the hull.
