Did actually go round deck 1and deck 2 to see if I could hear anything that might be a problem , these are the cabins where there might be an issue for some people.
Deck 1 = cabins 1836, 1855, 1916 &1962,
Deck 2 = cabins 2631, 2628, 2640, 2704
To be fair, this was only noise in the corridor and it might not go on all night and not everyone would hear it in their cabin.
As I said earlier my cabin was great with no noise issues
