Among the famous cruise lines offering services in Alaskan seas are the Royal Caribbean, Celebrity, Princess, Radisson, Norwegian, Holland America, and American Safari. Each cruise line has its own ships and itineraries, and is most active in the peak season between May and September.

The Royal Caribbean Cruise Liner is one of the most famous Alaskan cruise liners. Its main ship is the Radiance of the Seas, with sister ships Serenade of the Seas and Vision of the Seas. Royal Caribbean provides an eight-day, seven-night Alaskan cruise. Royal Caribbean Cruise Line specializes in cruising along frontier towns, and glacier cruising.

The Princess Cruise Line is highly recommended by cruise critics. Its huge ships are often called floating cities due to the vast number of restaurants, Broadway theatres, casinos, health spas, movie halls, lounges, discotheques and other forms of relaxation present onboard. Their popular ships are the Diamond Princess, Sapphire Princess, Coral Princess, and Island Princess. They have weeklong itineraries, and people can book them either during their northward or southward voyages.

The Celebrity Cruise Line is known for its fleet of large opulent ships like Zenith, Mercury, Infinity, Constellation, Summit, and Millennium. Celebrity has recently launched ships in the Xpedition class, which are made for adventure cruises.

Besides the huge cruise lines, small ships are also very popular. Small ships have better navigation ability and hence are favorites among adventure seekers. Lindblad specializes in its small cruise ships that can hold up to 120 guests. Holland America has five ships, namely Statendam, Veendam, Ryndam, Zaandam, and Volendam, which offer small cruises on the Inside Passage and Glacier Bay.

American Safari provides long as well as short Alaskan cruises in yachts. Their yacht Safari Quest has both five day-four night as well as eight day-seven night cruises. Safari Spirit and Safari Escape also conduct fortnightly cruises to Alaska. Most cruises conducted by American Safari are chartered, and the charter rates for the Safari Quest are about $58,000 for five days.
