My sister just got off the LOTS and had a promenade cabin. She too was concearned with the noise possibilities. I asked her when she got back and she said the noise from the promenade was not a factor. She did have a noise problem because she was also next to the service closet where the ice machine was. Apparently every morning the stewards came to fill the ice buckets for the day and they would bang the cart with all the metal ice buckets going in an out of the closet. But that kind of noice could happen in any kind of cabin if you had one in a bad spot....
