We alternate. one cruise RCI, the next Carnival. We are going on Royal Caribbean's Oasis of the Seas in April 2019, and have already booked Carnival Mardi Gras for April 2021. We book early to get the cabin we want. Carnival Vista, Horizon and Mardi Gras have the Havana areas. We book the Havana Cabana, a "balcony" which is more of a porch/lanai. The Havana bar and pool areas restrict access and only allow those staying in Havana staterooms access until 7pm each night. It seems as if you have the whole ship to yourself. Breakfast buffet set up nearby each morning and the specialty coffee/ MILKSHAKE area is just around the corner. We enjoy both of these cruise lines. If you go Carnival, and there are just two of you.... you'll appreciate the Havana class staterooms.
