Quest 4038 is a Category 12 inside cabin. It is located directly under the casino. I was concerned it would be loud. I heard nothing! It was a silent cruising experience. One night while sailing there was a storm. We heard nothing! Many of the passengers with outside cabins complained about the storm noise kept them awake. If you are an inside cabin cruiser and on a budget, don't be afraid to book the 4 inside cabins on deck 4. They are mid ship and low in the ship so there will be less ship movement and a comfortable ride.  Read entire member review.
