We had the experience of the Aft Suite on the Mardi Gras the past January, our room was on starboard side deck 12. We never felt "on display" and when sitting in any of the provided loungers only had a the sea view and none of deck 8 below.
We loved the room, view and balcony so much we have it booked for May' 23 on the Celebration and again in January '24 back on the Mardi Gras.
