Start with the sailing pattern. Princess runs multiple itineraries in Alaska, and they're not interchangeable. A seven-day Inside Passage sailing from Seattle hits the same ports as a ten-day sailing that adds more time in Glacier Bay or a different routing altogether. If you're liveaboarding for six weeks or eight weeks, you need to know whether you're doing back-to-back seven-day sailings, which means you're in and out of Seattle every week, or a longer sailing that gives you more time in port and fewer turnarounds. Turnarounds are brutal for liveaboards. You're packing, unpacking, dealing with new roommates or cabin mates, resetting your space. The fewer times you do that, the more you actually settle in.
The cabin type is where most people make their first real mistake. They look at a balcony cabin on the deck plan and think about the view. A liveaboard thinks about whether they can actually work, sleep, and exist in that space for weeks without losing their mind. A standard inside cabin on a Princess ship is roughly 160 square feet. That's smaller than a lot of studio apartments. If you're sharing it with another person, it's tight. If you're alone and you're spending eight hours a day in that cabin because of weather or port days, it's a cell. A balcony cabin adds roughly 40 square feet of outdoor space, but it doesn't add square footage to the cabin itself. The real upgrade for a liveaboard is a suite or a mini-suite, which gives you a separate living area, a bathtub instead of a shower, and enough space to not feel like you're living in a shoebox. Those are expensive, but if you're going to be aboard for months, they're worth pricing seriously.
The ship's age and amenities matter, but not the way vacation cruisers think they do. A newer ship has newer plumbing, newer HVAC, and fewer mechanical surprises. For a liveaboard, that's real. You don't want to spend a week in a cabin with a broken air-conditioning system in the middle of summer in Alaska. But you also don't need the fanciest ship in the fleet. You need a ship that runs reliably and has enough onboard infrastructure that you're not bored or frustrated after the first month. That means a decent gym, a library or quiet spaces, multiple dining venues so you're not eating the same food in the same room every night, and enough deck space that you can get outside without feeling crowded.
The crew matters more than the ship. If you're aboard for weeks, you're going to see the same housekeeping staff, the same dining room servers, the same bartenders. A good crew makes a liveaboard life tolerable. A bad one makes it miserable. You can't know this from a ship comparison. You find out by talking to people who've actually lived aboard that specific ship, or by booking a shorter sailing first and paying attention to how the crew treats long-term guests.
Port days and itinerary are the real decision. Alaska has limited sailing season, and the ports don't change much. But the amount of time you spend in each port, and how many times you visit the same port during your liveaboard period, matters enormously. If you're doing back-to-back seven-day sailings, you're hitting Juneau, Ketchikan, and Glacier Bay multiple times. That's either a feature or a bug depending on whether you want to explore deeply or see new places. If you're doing a longer sailing, you might hit fewer ports but spend more time in each one. For a liveaboard, deeper is usually better than wider.
The cost structure is where the ship choice actually becomes real. A newer ship or a larger ship typically costs more per night than an older or smaller ship on the same itinerary. For a one-week cruise, that's a few hundred dollars. For a six-week liveaboard, that's thousands. You need to know the actual per-night cost of each ship on your chosen itinerary, not the published brochure price. Last-minute pricing, shareholder onboard credit, travel agent rebates, and loyalty discounts all change the math. A ship that looks expensive at list price might be cheaper than a ship that looks like a bargain once you factor in what you actually pay.
The real question isn't which Princess ship you should choose. It's whether you're actually ready to live aboard for the duration you're planning, whether the itinerary matches what you want to see and do, and whether the per-night cost fits your budget once you've applied every discount and rebate you can stack. The ship is the delivery mechanism. The life you're building aboard is the point.
If you're comparing two ships on the same itinerary, ask yourself: Can I actually live in the cabin I'm booking? Will I go crazy doing the same ports multiple times, or is that exactly what I want? How much am I actually paying per night, and does that fit my monthly budget? Those questions matter. The ship's name doesn't.
