Island Princess: the real Panama Canal ship, on 17-day full transits
Island Princess measures 92,822 gross tons, 294 m long by 32 m wide. It has 15 decks, 12 of them open to guests, and 1,107 staterooms in 34 categories, 581 with a balcony and 20 wheelchair accessible. It carries 2,214 guests at double occupancy, roughly 2,657 with every berth filled, and 900 crew. Built by Chantiers de l'Atlantique in Saint-Nazaire and in service since 2003, it was named by Jamie Salé and David Pelletier, Canada's Olympic pairs skating champions. It is based in Fort Lauderdale for the winter, where its canal transits begin, and in Vancouver and Whittier for the Alaska season.
The whole canal, not just a passage through it
Its 32 m beam was dictated by the original Panama Canal locks, which take nothing over 32.31 m. Along with Coral Princess, Island is one of only two ships in the fleet that fit, and it is the one that made a career of it: from January to mid-April 2027 it runs back-to-back 17-day full transits between Fort Lauderdale, San Diego and Los Angeles, then repeats the pattern in December, as it already does in December 2026. Coral crosses the canal on repositioning voyages only. One detail costs real money if you miss it: those 17-day sailings are coast-to-coast one-ways, so book a multi-city air ticket rather than a return to the same airport.
What the 2015 rebuild gained, and what it cost
That year Princess removed a lounge and the aft part of the outdoor promenade to build 121 additional staterooms, raising double occupancy from 1,974 to 2,214. Those cabins, grouped aft where the old lounge stood, are the newest accommodation on board. The ship lost two things: the full outdoor lap of the ship, gone since 2015, and the two decorative cylindrical pods that topped its funnel. Regulars spot Island instantly by that bare funnel, while Coral Princess kept its pair. There is a further trade to accept: 240 more guests move through the same public rooms, so the buffet and the theatre feel tighter than on its twin.
Where it sails in the meantime, and which stateroom to book
It closes its Alaska season on 9 September 2026, runs down to Los Angeles on the 16th, then makes the 17-day canal crossing to Fort Lauderdale on 20 September. On 6 October it leaves on a 26-day transatlantic to Athens and comes back the other way on 31 October; December returns it to the canal. In 2027 Alaska takes it from 12 May to 8 September, then it crosses back through the canal in October and finishes the year in the Caribbean. Its last dry dock ran from 5 to 24 September 2024 at Fincantieri in Palermo. A midship balcony on Dolphin (9), Caribe (10) or Baja (11) genuinely changes transit day: you watch the Gatún and Miraflores locks from your own chair instead of competing for rail space forward.
The Medallion, The Sanctuary and a loyalty tier that climbs fast here
The ship is MedallionClass: the disc you wear replaces your key card, acts as your payment method, speeds up embarkation and lets you order food and drink from wherever you are. It locates you on board, which is what makes delivery possible and what bothers some guests; you decide whether other passengers can see that position. On transit day everyone is outside at once, so expect a busy network. The Sanctuary, up top, is the adults-only deck and it costs extra. As for the Princess Cruises Captain's Circle, it counts days as much as cruises: two 17-day canal transits put you at Platinum, five cruises or fifty days, inside a single year, with complimentary laundry and priority disembarkation attached.
Two ships to weigh against Island Princess
Diamond Princess is larger and better supplied with dining rooms, but it stays in Japan and Singapore all year. Sapphire Princess was refitted in October 2025 and boards at the Port of Québec in autumn 2026, worth considering if flying is what puts you off.
Who Island Princess is wrong for
Morning walkers first: the shortened promenade shows up on day one and there is no substitute on board. Next, anyone looking for the ship to be the attraction. The hull dates from 2003, stateroom bathrooms are narrow, there are only two specialty restaurants, no cantilevered glass walkway and nothing close to the glass dome on the newest hardware. Finally, families with small children: a 17-day canal transit is an extraordinary geography lesson for a 14-year-old and a very long week for a 6-year-old.
