This is most unfortunate. I looked at the deck plans for the Anthem and saw nothing above, below or next to you that could be causing the sounds that you explain! Usually, the sounds you describe can be associated with a venue somewhere near your cabin such as a bar, buffet or restaurant. In your case...nothing. All there is around your cabin are more cabins. The maintenance staff and RCCL is aware of the issue but they can't explain it either? I hope you strongly complained to RCCL verbally and in writing because if this is an existing issue they are obviously aware of, yet seem to be ignoring it, they should be at least offering some kind of compensation for your cruise. After a busy day in port or on sea, a good nights sleep is what prepares you for the next day's events. On a cruise, you don't want to miss a day because you have to try to catch up on sleep during the day by napping. Best of luck and hope your future cruises are better. Bon Voyage....
