This was our second time sailing with Oceania (the other in 2005 Barcelona to Istanbul). We like the smaller ships (less than 700 passengers) and the port intensive itineraries of Oceania. The ships are very nicely appointed and have a "country club casual" ambience. No need to pack all that formal wear.
Although staterooms are known to be on the smallish side, they are very well laid out and comfortable. In 2005 we had Concierge Level balcony Stateroom which was very nice, however on this cruise opted for the somewhat larger penthouse suite which had a bathtub and came with butler service. Our butler was extremely pleasant and efficient but did not find having a butler significantly contributed to our enjoyment of the cruise. Although I was completely satisfied with the concierge level stateroom, my husband enjoyed the extra space of the penthouse suite especially as was 14 day cruise.
Dining on Oceania was wonderful experience. Maybe not quite ***** but certainly much better than many of the larger cruise lines. We generally dined in the main Dining Room - no set seatings so could dine when you pleased. Had the option of dining alone, with group or to be placed at an open table. Many of the tables were for 2 but well positioned so could have a private meal but were at the same time conducive to meeting others. Particularly enjoyed the speciality Italian restaurant Toscana and dined there on a number of occasions. Polo Grill was also nice but menu limited to fairly standard steaks & chops. For breakfast we generally ordered room service & ate on our balcony or had croissants & coffee up in the Horizon Lounge (very quiet). We are not buffet type people and generally avoided the buffet except to pick up a few appies to enjoy in our stateroom. Unlike other cruise lines, Oceania do allow you bring your own liquor aboard to consume in your stateroom. Can also bring your own wine to dining room but charged a corkage charge so not worth extra cost. Normally we would order bottles of wine with dinner, and what was not finished was stored by the wine steward for the next day.
Without set seating, you did not always have the same service staff. However being a smaller ship and longer cruise we did get to know a number of the staff. Service was exceptional and friendly.
Where Oceania falls down is on entertainment and shore excursions.
Entertainment - The house orchestras were OK but the headlined acts were so so bad. I generally would walk out but my husband would stay because they were not only bad but they were terrible! One of the entertainers on our Baltic cruise was the same as on our Mediterranean cruise in 2005.
Oceania is adult oriented and do not have children's/teen programs. Not a "party boat".
Shore excursions: Grossly overpriced and Oceania have the habit of canceling excursions at the last minute if they don't have enough people signed up. Excursion desk staff, although pleasant, were unable/unwilling to provide port information other than related to their tour. Generally a local tourist official would board when we got into port but a bit late for advance planning. For St. Petersburg , Oceania gave us the impression that it was very difficult to get a visitors Visa for Russia and it would not be possible to get off the boat without taking one of their excursions. Fortunately at the last minute we learnt this was not the case & booked 3 day tour with Alla Tours which was fabulous. Best advice is to try and pre-arrange own tours or get a good guide and do it on your own.
With this last cruise, had a few problems pre-cruise with our flight deviations. Our itineraries were different as husband was returning a week later from UK. We received our flight confirmations from Oceania and all seemed OK as we had requested until we called the airlines to book our seat assignments. Evidently my husband's reservation had been changed & he was scheduled to fly out to Stockholm a day later than me. Took over a week to rectify.
Would I sail again with Oceania - probably yes but am a bit hesitant because I enjoy going to the evening show as part of the cruising experience.
