It's hard not to revert to hyperbole with Alaska. Here lie more than enough towering snow-capped mountains, breathtaking calving glaciers, extraordinary wild animals and quirky (if overtrafficked) frontier towns to wow hundreds of thousands of cruisers annually. With more than two dozen mainstream ships plying Alaska's island-filled southeast region from May to September, passengers certainly have options.

This chart features a representative from every major line in the mainstream and luxury markets, from the intimate and upscale Silver Muse to mega-ships like Norwegian Bliss. (For those who'd prefer to cruise with no more than 100 passengers, see our rundown of small-ship cruise lines in Alaska.)

Each of the 12 ships, which were hand-picked based on their popularity among all cruise options in Alaska, caters to a different type of traveler. Families on a budget might find the most "bang for their buck" onboard Carnival Spirit, while couples looking to splurge can pamper themselves with Seven Seas Mariner's lavish suites and all-inclusive fine dining.

Familiarize yourself with the biggest contenders' itineraries, exclusive regional offerings and more to determine which is the best Alaska cruise option for you.
