Lovely ship: Marina is truly delightful. She can seem a little beige in places but that is offset by some very interesting and colourful artworks on the walls. And they weren't for sale!
The Grand Dining Room is light and airy with a fabulous central crystal chandelier; the specialist restaurants interesting in their layout and appearance (loved the water wall in red Ginger), while a Lalique inspired staircase leading up from the Reception area expressed understated elegance. Great ambience.
Terrace buffet tables are a little crowded together but the food service area was spacious. Cabins (sorry but being a Brit I struggle to call them staterooms) are spacious and well appointed. Entertainment was average. Cigarette smokers are catered for in one area on the pool deck and in a totally separate section of the Horizons lounge, which seems a reasonable compromise. Didn't try the Artist's loft or the cooking lessons but both were praised by those who did. Didn't even look for the gym or spa.
Oceania Marina.
Cabin 7130, a PH3 at the stern is slightly narrower than other PH cabins which proved problematical only when my wife was busy at the dressing table and I wanted to get past. It has a fantastic L shaped balcony that is possibly the largest on the ship. However the room is quite noisy when docking (putting a positive spin on it you could say it provides a free early morning wake-up service) and was dreadful when we were tendering in heavy weather and the ship had to constantly use its engines to maintain station.
Very comfortable bed; good lighting; small walk-in wardrobe. Nice granite and marble bathroom with a full size tub; shame about the plastic walled shower cubicle.
