Carnival Cruise Line will sail its 2,600-passenger Carnival Adventure from Seattle between May and September 2028, marking the 2001-built vessel's first U.S. deployment and adding a third summer ship to the line's Pacific Northwest lineup.

The schedule, drawn from Carnival's recently published 2028 deployment, centers on seven- to nine-night roundtrip Alaska cruises plus a closing 16-night Hawaii-and-Canada voyage. Two Carnival Journeys sailings anchor the extended programming: a nine-night cruise to Sitka in September 2028 and a 16-night itinerary that calls at Nawiliwili, Honolulu, Kahului and Hilo before returning to Seattle.

How does the Adventure's arrival shift West Coast capacity?

The 109,000-ton ship joins the Carnival Spirit and Carnival Legend in the line's 2028 West Coast setup. All three vessels will operate from Seattle, Long Beach and San Francisco between April and September 2028, covering Alaska, Mexico and Hawaii across the season.

That three-ship footprint gives trade partners a fuller Pacific portfolio out of three U.S. homeports. Carnival is positioning the Adventure as an Alaska specialist for its debut season. Seven-night roundtrip sailings include port calls at Juneau, Skagway, Ketchikan and Victoria, paired with scenic cruising through Endicott Arm Fjord and the Inside Passage.

The September Carnival Journeys sailing to Sitka gives agents a longer-experience product to pair with the standard Inside Passage routing. The 16-night itinerary extends the booking window well past the usual Alaska close.

What is the ship's distribution history?

The Adventure did not arrive through a newbuild order. Princess Cruises built the vessel in 2001, and P&O Australia operated it for four years before the Australian brand combined operations with Carnival in early 2025. Since that transfer, the ship has continued sailing from its Sydney homeport under the Carnival flag, serving the Australian summer market.

Starting in 2027, the line will broaden the Adventure's itinerary mix in Australia ahead of the trans-Pacific repositioning to Seattle. The timing lines up with Australia's winter season back home for the 2028-29 period. Carnival did not disclose the repositioning voyages connecting Sydney and Seattle, which typically carry above-average pricing for travelers booking one-way segments.

What does this mean for travel sellers?

For travel advisors, the addition lifts Carnival's berth capacity on the West Coast during peak Alaska season without a newbuild cost on the supplier's balance sheet. The Carnival Journeys branding on both the Sitka cruise and the Hawaii-Canada sailing positions the Adventure for longer-stay bookings. That category tends to draw higher-value travelers and longer lead times.

The 16-night itinerary in particular opens a Hawaii option outside the typical seven-night market, an underexposed product for sellers focused on the central Pacific. Carnival now anchors three ships in the West Coast market from April through September 2028. That footprint supports cross-promotion across Alaska, Mexico and Hawaii itineraries and could simplify group bookings and air-deviation packages for agents working Pacific routes.

The Seattle base also lets the line intercept Alaska Fly & Cruise demand, a high-margin category that depends on tight homeport logistics.

The Adventure will return to Australia for the 2028-29 winter following the U.S. summer. That move leaves open whether Carnival will keep the ship in North America for the 2029 season, a decision that will shape how sellers plan repeat business on the vessel and whether the line commits to year-round West Coast capacity.
