Oceania Arietta deck 4 plan (Theatre-Restaurants1)

Medical Center (not shown, on Deck 3, Forward) is the ship’s dedicated healthcare facility where guests can receive professional medical care during their cruise. Like medical centers on other Oceania ships, it’s staffed by qualified medical professionals — typically including a licensed doctor and registered nurses — who are trained to provide routine and urgent care while you’re at sea. These facilities aren’t full hospitals but are equipped to handle a wide range of common medical needs, such as treating minor illnesses (like colds, flu symptoms or dehydration), managing injuries (such as cuts, sprains or minor burns), assisting with chronic condition concerns, and stabilizing more serious conditions until further care can be accessed if needed. The medical team also has access to basic diagnostic tools and emergency equipment — including items like oxygen, defibrillators and standard monitoring devices — to support patient assessment and immediate treatment. The Medical Center typically operates with scheduled clinic hours for non‑emergency visits, during which guests can consult the doctor or nurse for health concerns and basic diagnostics. Outside of these hours, the medical staff remains available around the clock for emergencies. There’s usually a small onboard pharmacy stocked with commonly used medications, though it’s not as extensive as a land‑based facility, and many prescription services or specialized treatments may not be available. It’s important to note that medical services onboard are not included in the cruise fare, so consultations, medications and treatments are charged separately to your onboard account. Guests are strongly encouraged to carry travel medical insurance that covers care at sea, including potential emergency evacuation if more advanced treatment is necessary ashore.

Sonata Lounge (Theatre/Show Lounge) serves as the main entertainment and performance venue. The space is designed to host evening live performances, production shows, and themed entertainment, making it one of the central social hubs for passengers after dinner or during scheduled entertainment times. It’s typically where the ship’s production team puts on large‑scale musical and dance performances that can include Broadway-style shows and other staged events, and it often doubles as a space for lectures, presentations, quizzes and enrichment talks during the daytime when shows aren’t scheduled. The lounge generally features comfortable tiered seating facing a stage area, good sightlines from most seats, and professional lighting and sound systems to support high‑quality performances. Because it’s a dedicated entertainment space, the atmosphere in Sonata Lounge is more formal than in casual bars or lounges — it’s where guests gather to enjoy planned entertainment that’s part of the cruise experience rather than drop‑in socializing.

The Theater hosts 4 main show productions developed by a professional team of producers, technicians, and performers to bring Oceania's shipboard entertainment to the highest level. The first three productions are titled "Into the Night", "Headliners", "The Anchor Inn", and "The Music Triangle".

• "Into the Night" (choreographed by Britt Benae Stewart. He is an American professional dancer and choreographer on the dance competition TV series "Dancing with the Stars" (a dance-themed production mixing dancing with styling and American Idol-like entertainment).
• "Headliners" is a VIP concert showcasing a resident cast/crew (vocalists and instrumentalists) performing some of the world's most popular songs from the repertoires of music icons like Bee Gees, Cher, Celine Dion, and Adele.
• "The Anchor Inn" is a UK-themed song-and-dance production set in the "Anchor Inn Pub" where a group of professional musicians celebrates British music's "good times" by recreating some of Britain's greatest hits by celebrities like Shirley Bassey, Tom Jones, Rod Stewart, Dusty Springfield, and Madness.
• "The Music Triangle" show is themed on the history of music.

LYNC Digital Center (digital help desk/connectivity services) is a technology‑focused enrichment and connection space and part of the ship’s expanded learning and lifestyle programming. The center is designed to help guests boost their digital skills and stay connected during the cruise through complimentary classes and interactive sessions. At the LYNC Digital Center, passengers can participate in workshops covering topics such as smartphone photography, videography, social media tips, photo editing and other personal tech skills, all led by knowledgeable Digital Concierges who provide hands‑on guidance and personalized tips in small‑group formats. In addition to learning opportunities, the LYNC Digital Center functions as a comfortable social and tech hub where guests can connect with friends and family, edit and share their travel photos, access high‑speed connectivity, and even tackle business‑oriented tasks if needed. The space is equipped with the technology and support to use modern devices effectively while at sea, leveraging strong onboard Wi‑Fi capabilities (such as Starlink® Wi‑Fi) to help guests stay in touch both on and off the ship.

Opus Lounge is a stylish bar lounge located amid the social and culinary venues on Deck 4, positioned alongside the Sonata Lounge and other public areas. The lounge offers a range of cocktail and social experiences, blending inventive mixology with a relaxed yet refined atmosphere where guests can enjoy drinks and conversation before or after dinner. The ship’s new lineup of lounges places an emphasis on craft cocktails and elevated drink moments, with references to experiences like a tableside‑prepared Old Fashioned at Opus Lounge — suggesting a focus on signature cocktails, attentive service, and a polished yet welcoming vibe. In context with other lounges on the ship, Opus Lounge is part of a broader mixology program that includes creative drinks, classic spirits, refined pours and bespoke pairings designed to enhance the social and evening experience onboard.

La Table (aka La Table par Maitres Cuisiniers de France) is a brand‑new, ultra‑exclusive fine‑dining restaurant introduced with Oceania Sonata in 2027. The venue is notable because it is the only restaurant at sea launched with the endorsement of the prestigious Maitres Cuisiniers de France (Master Chefs of France/MCF), a globally respected institution devoted to French culinary arts. Chefs from this association, along with Oceania’s own Executive Culinary Directors, create rotating menus for the restaurant that showcase exceptional French cuisine at its finest.

• MCF is a prestigious global association of top French chefs dedicated to preserving, promoting, and transmitting French culinary art and heritage, focusing on excellence, tradition, innovation, and quality products. MCF members act as ambassadors, training apprentices, organizing cooking competitions and championing French regions' cuisine and high-quality ingredients.
• The 18-seat La Table is a dinner-only VIP restaurant (at a surcharge), and reservations are required. It offers a rotating menu crafted by the ship's Executive Culinary Directors, and the MCF chefs Alexis Quaretti and Eric Barale. The venue also revives Oceania Cruises’ signature Dom Perignon Experience, delivering a 6-course tasting menu paired with three vintage Champagnes.

Toscana is one of Oceania Cruises’ signature Italian specialty restaurants. The 96-seat dining venue showcases Italy’s culinary heritage. The menu focuses on classic Italian flavors rooted in family traditions and regional techniques, especially from Tuscany and other northern Italian regions. It features authentic, beautifully prepared Italian dishes such as octopus carpaccio with Champagne vinaigrette, artichoke and Parmesan timbale with black truffle sauce, homemade gnocchi with pesto, lobster risotto, and pan‑fried sea bass. Toscana is a dinner‑only complimentary restaurant that requires reservations. Oceania Vista's godmother (chef Giada De Laurentiis) created two signature dishes served only in the restaurants Toscana and Grand Dining Room.

Polo Grill (steakhouse specialty restaurant) represents Oceania Cruises’ classic steakhouse experience. The refined, dinner‑only venue focuses on premium grilled and seared dishes in the tradition of an upscale American steakhouse, emphasizing rich flavors and quality ingredients. Polo Grill's ambiance is elegant but comfortable, featuring dark wood decor, crisp white table linens, and plush leather seating that creates a club‑like atmosphere. The menu centers on high‑quality beef cuts — often USDA‑certified Angus that’s aged to enhance tenderness and flavor — prepared to guests’ preferences. Alongside steaks, the offerings usually include premium seafood such as grilled swordfish or whole Maine lobster gratinée and classic starters like a traditional Caesar salad. Polo Grill is open for dinner only and typically requires reservations. It's one of the complimentary specialty restaurants, but it is more formal and culinary‑focused than the casual dining venues, appealing to guests who appreciate classic steakhouse fare, attentive service, and a fine‑dining ambience.

The Lobby Hall houses the Reception Desk (guest services/check-in area), Destination Services Desk (information and shore excursions), the Concierge Desk (concierge services), and the Future Cruise Sales Desk (onboard cruise booking).

Adjacent to the Lobby is the Library (quiet reading and relaxation lounge) providing 1000+ books, many of which are port/destination guide books.
