Booked Oceania as it was deemed to be the next level of luxury up from the standard lines (as the price would also encourage you to believe). Ship is nicely decorated, but nothing that special - pretty standard. Service is excellent, this is one well trained staff.
Oceania prides itself on having some of the best food on the sea and you will not be disappointed. The 2 specialty restaurants (that most cruises charge a fee to eat at) are complimentary on this ship.
Booze is on the pricier side and the excursions are also outrageous. On our ship, most people were doing their own touring because the excursions were so overpriced.
