As this was our first visit to Cuba (but by far not our first cruise), we were a bit nervous about visas, licenses, etc. for US citizens. Oceania arranged for our Cuban visa, and we checked “Support for the Cuban People” on our license application. We had no trouble exiting the ship and finding our independently-arranged excursion guides. (We booked all of our tours ahead of time. Be sure to choose OFAC-compliant tours if you are a US citizen booking tours on your own rather than through the cruise line.)
We were also a bit nervous about the condition of the ship, given some negative comments we’d read. We booked a concierge level veranda suite about 18 months prior to our sail date. The bathroom was remarkably small and not at all luxurious. The sleeping area is also very small, but of course, the Sirena is a relatively small ship with fewer than 700 guests. The bedding was very comfortable, especially after we requested a regular blanket. The down comforters are quite warm!
Public rooms were in good condition, but we heard some complaints about missing tiles in the pool area.
