I was booked in a penthouse suite, 8035, and found it spacious and well appointed. Bedding was comfortable. Balcony area was adequate with two relaxing chairs, two ottomans and a small cocktail table. Bathroom space is smaller than Seabourn, but larger than SeaDream. Bulgari amenities, Q-Tips, cotton pads etc were provided. Erik, the butler, provided great service without being intrusive. Even cashmere "throws" were provided in the stateroom in case you needed a cozy wrap. Champagne was iced down upon arrival and complimentary soda and H20 was refreshed throughout the cruise.
The gym/spa was large for a "small" ship. It had all of the usual equipement...treadmills, bikes, elipticals, free weights and Precor stations. Classes (spin, yoga etc) were offered, often requiring and extra charge of $11.00 per class. The locker room was nice...razors, shaving cream, shampoo, conditioner, combs and body lotion were provided gratis. The steam-room in the men's locker room was large and rarely used. All in all, you could get in a great workout.
Embarkation/disembarkation was simple with NO wait time. The only time I encountered any lines were on tender days but even then wait time was brief.
Shore excursions were well organized, but overpriced. Better to go on your own. Drinks could also be on the pricier side, but happy hour was offered daily from 5pm-6pm.
One important note is that Oceania deals with a bank located in Ireland. This means ALL purchases charged to your credit card may incur a foreign transaction fee. If you contact Oceania, they will refund this charge, though it is easier to use a fee free card (ie:Capital One).
It was a very enjoyable cruise and I wouldn't hesitate to book with Oceania in the future. I did miss the marina on Seabourn/SeaDream.
