Hello, Sachasmom! We were on the Voyager in 785 Penthouse C aft December, 2019 (right before COVID). We did not notice any sound at night from any lounges. The vibrations were minimal. Pies4u is correct, mostly noise and vibrations during docking times. We were in the South China Sea (notorious for choppy conditions) and we had no problems with vibrations while at sea. We love the Voyager and have been on her six times and the Explorer two times. I believe that the Navigator is the oldest of the Regent ships. The Mariner is the closest in size and layout to the Voyager, but not exact. We enjoyed the little bit of extra room in the Penthouse C as opposed to our regular Concierge D. We also loved the slightly larger balcony. The staff in August, 2023 on the Voyager (Iceland to UK), was top notch. Go for it!
