I am a fan of Oceania, having travelled on a few of their ships. I find the cruise line perfect for us, not to big just the right amount of quests on board.
We found the ship clean, comfortable and the food excellent, the quality and variation excellent, especially Jacques and Red Ginger.
One complaint I have is with the lounge chairs around the pool. It never ceases to amaze me how selfish some guests can be, they are not happy with one deck chair, but, they have to hog two, one in the sun and one in the shade. This is at the cost of other guests not be able to find just one deck chair to enjoy themselves around the pool. There has to be a way to control this, it is such a selfish act and has to be stopped.
