Oceania Cruises dress guidance

• Country-club casual or elegant resort wear is the normal evening standard; tuxedos and gowns are not required.
• Official dining guidance asks guests to avoid jeans, shorts, T-shirts and tennis shoes at dinner; the onboard program remains the final voyage-specific guide.

Packing suggestions are Deluxe Cruises editorial guidance; the cruise line's final documents and the weather forecast control the last check.

• Aquamar Spa + Vitality Center, dining venues, lounges, a pool, entertainment and enrichment are core fleet features, but the exact venues and programs vary by ship.
• Do not describe a cooking school, spa terrace, casino, sports deck or particular restaurant as fleetwide without checking the selected ship.

Venues, hours, inclusions, equipment, and operating conditions can vary by ship and sailing. Deluxe Cruises will reconfirm the details for this departure.

• Official life-on-board material publishes fitness equipment and complimentary group classes, with wellness consultations and a walking or fitness track on applicable ships.
• Spa facilities, class schedules, participation rules and outdoor sports vary by ship and voyage and should be reconfirmed.
