Thank you! Sailing Holland America on Zaandam for the first time in the fall. We have one of the secret aft cabins. Do you notice a lot of shaking in the aft? We were on a Princess ship a couple months ago. We had to move our cabin from the aft to the center of the ship. Plenty of empty rooms so it was not a problem. Princess was great letting us move. I’ve never experienced that kind of shaking on a ship before.
