This is one of the older ships and we have sailed on Sirena and its sister ships many times. Azamara has a couple of these ships and Princess at least one. We love the small ship experience and the ports we can access because of the size of the ship.
On the second day out of our cruise, all the lights went off and the ship was still. That lasted about 10 minutes and the passengers were assured that it had been fixed. We missed our fist port, Aruba ostensibly because the seas were rough and we had head winds. The captain had two full days to make it to Aruba, and while there were white caps on the swells, it was not terribly rough. We were late to another port because of the same reason. We left St. Barts on Weds. afternoon to start the trip back to Miami. The sea was very calm and the weather beautiful for the next couple of days. We were informed on Friday morning that we would miss our debarkation time in Miami by 4 hours. The reason given was "currents". Oceania made a big mistake with this excuse, there were a great number of well traveled cruisers on board. The only conclusion the passengers could come to was the ship has engine problems and they could not make the speed that was expected. In fact we docked in Miami at 11:30 am instead of 7:00 am and you can imagine the disruption to travel plans that caused. Of course, if you made your own arrangements, you would probably be out a lot of money due to changes to airline tickets etc. How unfair of Oceania to give such a story to its passengers and to make the passengers pay for their problems. It was NOT the weather.
Oceania did a great job renovating this ship, its looks quite beautiful however they have a couple of areas that are a big problem. The smallish staterooms have the smallest bathrooms you can imagine. The designer decided that clear glass doors on the tiny shower would make the bathroom look bigger and so replaced the shower curtains. Unfortunately you can not get in or out of the shower without touching a cold wet glass with some part of your body. Turns out the shower curtains gave greater flexibility. Some of the male passengers took to the fitness center for their showers!
