My daughter and I are doing mexican riviera end of March and just got our travel docs today. Carnival upgraded us from an 8b to a category 11 suite for no extra cost because they needed our cabin for a group. We were booked upper deck mid ship and now have the suite on upper deck but it is in the very back of the ship. Altho I'm thrilled for the upgrade, am kind of concerned about location. Anyone have experiences with back of the ship cabins? Is there more motion than mid ship?
