Alaska and Hawaii Cruise: Can You Really Do Both on One Ship?

Here's what most pages gloss over. A lot of listings say “Alaska to Hawaii,” and then you open the day-by-day and it's a ship leaving Vancouver and heading straight across the Pacific. Not one glacier.

So before you get excited, figure out which version you're looking at. There are three, and they are very different trips.

I'll walk through all three, when they run, why the routes look the way they do, and how to keep costs sensible. I'll also tell you who should skip this one.

The three ways to get Alaska and Hawaii in one trip

Here's how to tell them apart at a glance. I've left fares out on purpose, because they swing a lot by date and cabin.

The middle row trips people up. It's a lovely trip, but it's a Hawaii trip with a long Pacific crossing, and Alaska only shows up in the name of the departure port.

Is there one ship that visits both?

Sometimes. These are the rare ones, and they change year to year, so read the examples below as things that have been offered and confirm current dates with the cruise line.

Norwegian Spirit, 16 nights (summer 2026)

Norwegian Spirit ran four 16-day Alaska and Hawaii cruises from July 15 through September 2026, alternating between Honolulu to Vancouver and Vancouver to Honolulu. The Honolulu departures visited Hawaiian ports such as Maui and Kauai, crossed the Pacific, then called at Alaska ports including Icy Strait Point, Sitka and Ketchikan before ending in Vancouver. Those dates are now behind us, and I haven't found a 2027 repeat, so this is a “watch for it” option.

Holland America Noordam, 28 nights (fall 2026)

Holland America's Noordam sailed a 28-night “Glaciers & Volcanoes: Alaska to Hawaii” voyage, roundtrip from Seattle, from September 6 to October 4, 2026. Trade coverage lists Alaska stops including Ketchikan, Sitka, Hubbard Glacier, Anchorage, Kodiak and Dutch Harbor, then five sea days to Nawiliwili, Kahului and Hilo, with an overnight in Honolulu. That's a month away from home, so it suits retirees or flexible schedules better than a school-break family.

Carnival Legend, 16 nights (2027)

This is the one to watch out for. Carnival's 2027 plans include a 16-day Journeys Hawaii cruise from Seattle on September 21, 2027, visiting Honolulu, Hilo, Nawiliwili, Kahului and Victoria, BC. It's a Seattle roundtrip with no Alaska ports. Same ship that does Alaska all summer, different trip.

When do these repositioning cruises run?

Two windows: spring and fall, because that's when ships change regions. In the fall, ships that spent summer in Alaska head south, and in spring they come back north for the next Alaska season.

Here are the 2027 Royal Caribbean examples I could confirm as of October 2026. Dates and nights come from schedule trackers and Royal Caribbean coverage, and they do shift, so verify before you book.

One tracker shows the September Anthem sailing at 8 nights on a different date, so confirm the exact date and length with the line before you buy flights.

Notice what's missing from those rows? Alaska ports. These are the cross-the-Pacific-and-enjoy-the-islands version, which is great, just different.

How many sea days are we talking?

Plenty. On the Anthem Sept 26 sailing, one tracker counts six days at sea and three in port. On Carnival's Seattle Hawaii cruise, you get five sea days out and five back. If you tend to get restless at sea, read the “who should skip this” section before booking.

Why the routes look so odd

Ever wonder why so many Pacific cruises start in Vancouver, or why a Seattle Hawaii cruise stops in Victoria? There's an old law behind it.

The Passenger Vessel Services Act of 1886 restricts foreign-flagged ships from carrying passengers between U.S. ports unless the voyage meets certain conditions. A University of Hawaii research paper walks through how that shapes Hawaii cruising, and the Federal Register notice lays out how Customs and Border Protection treats voyages that include a distant foreign port.

The takeaway for you: a foreign-flagged ship can't just carry passengers Seattle to Honolulu on a whim, so lines build in stops like Victoria or start in Vancouver. The cruise line handles all of it. I'm not a lawyer and the rules have exceptions, so treat this as background, not legal advice.

How to save money on an Alaska and Hawaii cruise

I'm all about traveling more without spending more, and repositioning is one of the few cruise styles where that can really work. I can't promise a savings amount, because it depends on the sailing and cabin, but these are the levers that matter.

Why the per-night price is often lower

One-way sailings with lots of sea days appeal to fewer people than roundtrips, so lines often price them to fill cabins. In the Royal Caribbean examples above, trackers listed starting fares in the high hundreds per person for 8 to 10 nights. That's a pattern, not a guarantee, so always compare the full cost, not just the cruise fare.

Add up the hidden costs before you celebrate

• One-way airfare. You'll fly home from Honolulu or fly out to start. Price flights before you book the cruise.
• Hotel nights. Arriving a day early is smart on a long flight. For Seattle departures, I compare a pre-cruise hotel in Seattle against the cruise line's hotel package.
• Gratuities and extras. Daily service charges and drink packages add up fast on a 16-plus night trip. Check each line's current policy on its own site.

Free things to do in the Hawaii ports

Honolulu, Hilo, Kona and the Kauai and Maui ports all have beaches and walks that cost nothing. For specifics, see my guides to the Honolulu cruise port and Waikiki and Kona and Hilo on the Big Island, including how tendering works in Kona.

Save your excursion budget for the one or two things you truly can't do on your own. Viator tours and shore excursions are worth comparing against the ship's prices. Just check the return time carefully, because a ship will only wait for its own excursions.

Who should skip this

A repositioning cruise isn't for everyone. Here's who I'd steer elsewhere.

• First-time cruisers who love ports. Five straight sea days is a lot for a beginner. A roundtrip Hawaii cruise gives you more island time. Start with my cruise to Hawaii overview or the 7-day Hawaii cruises from California.
• Anyone who mainly wants glaciers. Most Vancouver to Honolulu sailings have no Alaska ports. Do a real Alaska cruise instead, and the best 7-day Alaska itinerary comparison will help you pick.
• Families tied to the school calendar. Fall and spring sailings land during the school year in most places.
• People prone to seasickness. Open Pacific crossings can mean swells. Ask your doctor about options before you go.
• Anyone who wants a short trip. The combined itineraries run well over two weeks.

If you'd like a smaller-ship Hawaii experience instead, I covered small ship Hawaiian cruises and who should skip them.

What to pack for two climates

This part is fun and a little annoying. You need rain gear and a swimsuit in the same suitcase.

Layers do the heavy lifting. For Alaska days, a good shell matters, and I wrote about choosing a waterproof jacket for an Alaska cruise. If you want to browse, packable waterproof rain jackets are the type to look for, ideally with a hood. Add a warm hat, then reef-safe sunscreen and a rash guard for the islands.

My cruise packing list covers the basics, and if your group wants matching shirts for the islands, my Etsy shop offers free name personalization.

Your questions, answered

One last thing before you start comparing

If you only do one thing first, decide whether you want Alaska ports or just a one-way Pacific crossing. That single choice sorts almost every listing for you.

And if you're still on the fence, a roundtrip Hawaii cruise plus a separate Alaska trip is often the easier, more flexible plan. I'm happy to price both side by side so you can see the real numbers.
