We sailed on the Vista before Covid. Love the Havana area. Totally worth it.
my wife loved the swing and Lanai. I thought I would miss leaning over the balcony rail and seeing the ocean. Wasn’t the case. I too loved the lanai. The Havana pool area is awesome. No young kids. Quiet and at times feels like your own private ship. Access to your room from the lanai area is nice. You dont have to go to the interior to access your room.
we love Havana cabins so much we just booked a Cabana room for the Panorama on August 6 and the Horizon for April 15th, 2023. If you have more detailed questions let me know.
