Marc, 914 and 915 are our favorite Penthouse C suites on Mariner. They are quiet, shower suites without a pole. You also have more privacy on your balcony since the balcony on the Mariner suite next door is in the middle of the suite and not adjacent to your balcony.
834 is probably our least favorite Penthouse C suite. It has a pole, is across the hallway from a noisy air conditioning room, and gets some noise when the tenders are being used or when crew members are doing maintenance on the tenders.
