We had Lido deck cabins on the Conquest and the Glory, which has the same basic layout as the Liberty. We loved the location so much, we will try to always get a cabin on that deck. Noise was never a problem - not even on the balcony. Sounds didn't seem to carry to the forward cabins. We spend so much of our day on the Lido deck, so it was great being in close proximity to our room. And the rooms are just past the stairs and elevators, so traffic wasn't a problem either.
