We have just returned from a trip to Russia on the Viking River Cruises Viking Helgi ship a holiday ruined by mechanical noise, which ensured I was entirely unable to sleep in the stateroom we had booked.
There was a consistent, loud and incessant humming noise and vibration in our cabin present whether the boat was moving or docked, making it unpleasant to be in the cabin in the daytime, and impossible to sleep at night.
I reported this noise and vibration as soon as we entered the cabin but was told there was nowhere else to move us to. I emailed Viking cruises and the only suggestion they made was to put in a complaint when I got home. Others were offered earplugs but I didnt even get that it would not have not helped anyway because the mechanical vibration being transmitted through the bed and pillow to my head was almost as bad as the noise.
There was a consistent, loud and incessant humming noise and vibration in our cabin present whether the boat was moving or docked, making it unpleasant to be in the cabin in the daytime, and impossible to sleep at night. The whole of the front end of the boat was subject to this vibration and humming but in our room, 226, these were amplified by a boxed column resonating with the floor and the bed. The noise and vibrations were so bad that in desperation a couple of times I took a blanket and pillows up to the Panorama Bar and slept on the floor. The Panorama Bar was so lovely and peaceful, much easier to sleep than in our so called Stateroom.
