Mariner of the Sea was a beautiful ship. It was easy to get around on and the staff was friendly. We were not hounded for drinks or picture taking which was fantastic! The Promenade was great - we stopped by there daily for snacks (not much that I could eat - not gluten friendly!)
We were in an inside cabin and true to RCCL - not very roomy. Had to crawl in to the bed but we knew that when we booked so it was not that much of a problem. We were far enough away from the elevators so there were no issues with outside noise! We had an awesome cabin steward and he was so good to us.
Food on the Windjammer seemed to be pretty much the same each day so after a few days - very boring. The staff that greeted us each time was annoying as they would say 'sanitize your hands'. How did they know a person didn't just wash with soap and water but I guess it is a good thing to stress keeping hands clean before eating to prevent illness from spreading.
9160...room was small but very clean, did not hear much noise.
