Princess has spent decades carrying large groups well, and it shows in the parts of a program that planners actually worry about.
The ships are laid out sensibly, the crew are practised at handling group movements, and the onboard technology makes the logistics of a few hundred people noticeably easier. Guests wear a small wearable device that opens their stateroom, orders a drink to wherever they happen to be standing, and helps them find each other across the ship. On a program where people are spread across eighteen decks, that is genuinely useful.
It also sails one of the strongest Alaska programs at sea, including land-and-sea itineraries that pair the cruise with wilderness lodges inside Denali. See the at-sea overview for the rest of the brands we represent.
