We were on the lido deck forward, port side room 9222. There is alittle bit of noise ,but not to keep you awake. It sounds like water running ,but I loved the room anyway, it didn't bother me in any way, I was just curious of why. As far as quiet, the hallways were always quiet cause those rooms only hold two in each room, so hardly any family's on that deck. I always love forward cabins. I used the balcony a lot.
