Been on Lido deck many times,both inside and out and no problems at all wherever you are on that deck. Enjoy.
Sorry, misread the question. Atlantic deck is fine. Have been in an outside cabin , and they have 2 portholes. No more noise thee than on the Lido deck. No smells no vibration. Cabin slightly smaller than on Lido deck but amount of wardobe and drawer space much the same.
