I was in 8064 last Spring. I worried that it would be noisy and it was very quiet. I expected chairs to be dragged and walking and I really never heard a thing. You'll have a great cruise. The ship is very nice and the staff is excellent. Have fun.
I had a cabin on the Celebrity Century in 1999 right below the Lido kitchen. I heard some noise but only for short time periods after meals and they weren't bad. Elevators close by are much worse. I really liked having only one flight between me the and Lido deck. It was very convenient. It was a good trade off!
