Stateroom was all we expected, at 6'-3" I had no difficulty taking a shower. Beds were great, never slept so well on a cruise ship before, wondering though, who actually does the thread counts on the linens. Room was kept beautifully, including removing the salt water spray residue on the patio that occurred after some rougher seas.
Having been in the food business "too many" years I congratulate them on their professionalism. Food quality, presentation and service were excellent. Though the speciality restaurants are greatly hyped, you would be hard pressed to find a bad meal or poor service anywhere.
If your going for the casino action be aware the machines are "tight" and the service and hospitality are horrible. High speed sarcastic dealers and grumpy pit bosses offered an attitude of total indifference. Upon complaining at the service desk, found out they are not employees of Oceania but a sub contractor. Suggest they do a little "mystery shopper" work.
Having been to Europe many times we didn't feel the need to book excursions. But, having heard from many others, its best to check around. We did book a private car in Livorno and had a fantastic time touring small cheese, ham and wine producers as well as the historic town of Voltaire at a fraction of the cost.
Embarkation was a breeze, professional, quick and very accommodating. The little wait for the staterooms to be ready was a perfect time to enjoy a leisurely lunch.
A couple of suggestions to future cruisers
Take a sweater, most of the dining rooms are chilly.
Take earplugs, seems most of the music venues try to test volume ability of their amplifiers.
All things being considered, I bought ear plugs, a new sweater and tickets for a Caribbean cruise on Riveria this winter.
