Disclosure - This is our 13th cruise - we have cruised on Princess, NCL, Royal Caribbean, Disney, and Holland America in the past and enjoyed every single one of them!!
Embarkation - No problem - not the fastest or slowest - after taking the train from Rome, walk a few hundred yards and go inside the port - catch the shuttle to the ship at the bus stop near the (closed at the time) tourist info booth.
Public Rooms - Not my personal taste in decorating and art, but nice.
Cabin - Despite being near the elevator and stairs on Deck 10, our cabin was clean, comfortable, and quiet. Oceania provided robes, slippers and a cashmere throw to use inside or out. Our supplies (frig and bathroom) were kept well-stocked. Great location for getting around the ship. Some raters have complained about the shower size, however, neither one of us thought it was small and personally I thought it was somewhat bigger than on other cruise ships.
Fitness Center - Did not use the spa, but used the fitness center - had no problem getting a treadmill or using the weights. However, it was not easy to find the toilet around there - it seemed like a maze to me - they hide it in a changing room.
Enrichment - Attended a couple of lectures from a professor (sorry - forgot her name) on Roman History - not heavy, but entertaining and informative. Also attended a talk given by a well-known sportscaster - again, funny and entertaining.
Dining - Excellent cuisine with the caveat that we did not eat in the Grand Dining Room, just the Terrace Cafe, Waves, and specialty restaurants. Also enjoyed the afternoon teas with live music.
Entertainment - Con Molto was the best ship show by their singers and dancers; we also enjoyed the comic Tom Drake.
Shore Excursions - We took three ship shore excursions - they were all very enjoyable and informative. In fact, on the day we were supposed to dock at Amalfi, the port was changed to Naples due to rough seas - the only ship excursion to actually go to the Amalfi coast (although not Amalfi itself) was the one we booked - Food and Wine Trails. Due to the rain we did not go the vineyard as planned, but had the wine tasting at the restaurant with that vineyard's wines and we were able to see the coast due to the drive to the small town we visited. The other two excursions were to Florence/Pisa and Taormina/Mt Etna. (Hint - if you are in concierge level, they usually had maps for the next port in the evenings in the lounge.)
Debarkation - No problems here either. (Hint - if you are leaving out of Marco Polo/Venice and aren't able to check in for your flight when you arrive, there are very, very few places to sit, unless you want to buy something in a restaurant - be prepared to stand until check in.)
Value for the Money - Overall just a little pricey - I don't mind paying higher gratuities on any cruise line for good service, and the cuisine was excellent, although not more than the cuisine "used to be" the few years we were cruising from about 1989 - 2000 or so. We would definitely go on Oceania again - just be prepared to pay a little more.
Overall - A FABULOUS CRUISE - GO AND ENJOY YOURSELVES!!
