Was on the Diamond last week. Aloha Deck A429 mid ship not far from elevators and I didnt hear any noise at all. We came out of elevator made a right and down maybe 4 rooms. I found it very convenient. Very little walking and the pool was one flight up.
no noise from the elevators, just ocasional rude people in the passageways especially in the wee hours of the morning..have had several cabins in that area and always like the the convience of elevators and stairs nearby.
