customers say

Oceania Sirena receives high praise for its attentive service, excellent food, and intimate small-ship experience. Most guests highlight the quality of the staff, well-maintained cabins, and diverse itineraries. However, some reviews note areas for improvement, such as inconsistent service in certain venues, crowded buffet areas, limited dining hours, and expensive or underwhelming excursions. Entertainment is generally good but not always up to the level of other aspects. Internet connectivity and communication could be improved. Overall, the ship offers a refined, relaxing cruise with a few operational hiccups.

"Oceania service staff is the best on the high seas...Thanking all who spoiled us xo"
"Staff was caring, kind, attentive; our concierge Sagit did a superb job on our room twice daily."
"Service not what we experienced in the past. Discussion among passengers trying to determine if it was cruise from hell or perhaps purgatory."

Destination: Panama Canal
As usual, Oceania was wonderful. The food was superb, the staff was top-notch and the casino dealers were just great. I had to sped several hours in the medical clinic and I was amazed. The level of care I received was much better than most US hospital emergency rooms. I had blood tests, an xray, iv and nebulizer treatments, and prescriptions dispensed. I was given the absolutely best treatment and I felt better in a day. US clinics and medical centers should really look at this model. The trip was a real pleasure and we put a deposit on a cruise for next year.

“Panama Canal Cruise”

Cruise Date: 12/21/2024
Destination: Caribbean
Oceania did not live up to expectations. They canceled the port in Mexico and also the all-day sea excursion in the Panama Canal! This was THE reason we booked this particular cruise. The replacement “excursion” was IMAX movie about the Canal. Seriously? Also, there was inadequate staff in restaurants, pool area and bars. The staff appeared overworked and stressed. Food was good. Nothing special I sadly must report. Altogether, we were disappointed and uncertain if we will book again.

Ship was nice, destinations mostly good but a couple of the ports had little to offer. Excursions were good but shuttle service on the ports was woefully inadequate. Too few shuttles, too far apart. Food was ok. Not nearly as good as I was expecting.
