Compare: 12 Cruise Ships in Alaska

You won't find any rock climbing walls or quirky pool games on Holland America's Nieuw Amsterdam, which prides itself on dining and a relaxed, traditional cruising experience. Service and food quality in the complimentary main dining room are top-notch, but for-fee restaurants like Pinnacle Grill (which now features a Sel de Mer pop-up venue once per week) and Tamarind make for splurge-worthy romantic dates. The ship tends to appeal to a more mature crowd, though you will see more families and multigenerational groups on Alaska cruises.

Thanks to a dry dock that welcomed new features like the Salty Dog Gastropub, Princess Cruises' Luxury Bed Collection and the "Voice of the Ocean" show (a spin-off of NBC's "The Voice"), Ruby Princess offers a fresh take on "The Love Boat" line. Pair that with fleetwide staples such as a lavish adults-only sun deck, Movies Under the Stars (complete with popcorn and cozy fleece blankets) and a partnership with the Discovery Channel, which offers a slew of activities for adults and kids alike, and you've got something for everyone.

An Alaska-themed hull design, alfresco restaurants and a 20,000-square-foot observation lounge are just a few of the reasons Norwegian Bliss is one of the best cruise ships to sail The Last Frontier. The 4,000-passenger ship boasts a handful of the features found on its sisters, Norwegian Escape and China-based Norwegian Joy, as well as its own unique attractions. With a variety of dining, entertainment and recreational options, cruisers will never go bored or hungry.

With a variety of dining venues, great kids' programs and adrenaline-pumping activities, Radiance of the Seas offers Royal Caribbean's best in a more modest size. The 2,112-passenger ship features the line's much-loved Giovanni's Table and Izumi Japanese Cuisine, a 200-square-foot outdoor movie screen, rock climbing wall and a nursery for babies and toddlers. Passengers range from young couples and singles to families and active retirees.

Celebrity Solstice has one of the best interior architecture designs at sea, and passenger flow is excellent. While the ship's passenger-to-space ratio is standard for the industry, the ship never feels crowded. Celebrity is known for its fabulous dining options and bars, but perhaps the unique feature of this or any other ship is the Lawn Club. This full half-acre of real grass on the top deck offers some of the best views onboard in a fun, relaxed atmosphere. The space includes an alfresco dining venue serving up fresh barbecue, games like bocce and mini-golf, and lounge chairs perfect for soaking up sun when the weather permits. Celebrity typically attracts sophisticated young adults and middle-aged couples, though you'll notice more families during the summer holiday.

The 1,754-passenger Disney Wonder is the pinnacle of family-friendly Alaska cruising. The line has tailored the experience onboard (kids' programming, dining) and off (unique, if pricey, shore tours) to appeal to cruisers of all ages. The ship, with its ocean-liner-style exterior and Art Nouveau interior, makes a statement: "elegance" and "family friendly" don't have to be mutually exclusive.

Full of "Fun Ship" touches like the Camp Ocean kids club and the Green Thunder water slide (pray for warm, sunny weather), Carnival Legend is a great value for families on a budget. The 2,124-passenger ship offers a variety of free alternative restaurants, activities and entertainment. Munch on celebrity chef Guy Fieri's famous burgers or indulge in Caribbean fare at the Key West-inspired RedFrog Pub after a game of mini-golf. Competitive families will also enjoy Hasbro, the Game Show, during which groups can compete against each other in a series of games for a chance to win prizes.

The 382-passenger Silver Shadow is an intimate, all-suite, all-inclusive luxury vessel with one of the most generous space-to-passenger ratios in the industry. There's also one crew member for every 1.3 passengers, who are accommodated in cabins ranging from 287 to 1,435 square feet. Suites are larger than the industry average, when it comes to luxury cruise lines, and bathrooms include double-basin vanities, Bvlgari amenities and full bathtubs and separate showers. Cabins aside, the ship features high-quality dining and included extras like select wine and spirits. Passengers are mostly well-to-do, older adults.

Luxury meets adventure on Seabourn Sojourn's Alaska cruises. The 462-passenger all-inclusive ship boasts a country club atmosphere with pampering service, and itineraries are packed with scenic cruising and lesser-known ports. Even better, you don't have to worry about missing any of the views, as all the ship's cabins face the outside. While restaurants and public spaces are opulently designed, the ship maintains a comfortable, friendly vibe.

Every cabin on the 700-passenger Seven Seas Mariner is a suite with a balcony and at least 252 square feet of space. The upshot: This is an all-inclusive luxury ship attracting both mature couples and affluent families. Passengers shell out up-front, but enjoy included amenities such as round-trip airfare, a luxury hotel stay, shore excursions, specialty restaurants, alcoholic beverages and gratuities.

Oceania prides itself on fine dining and an upscale yet comfortable ambiance -- and Regatta is no exception. The 684-passenger ship features creations of celebrity chef Jacques Pepin in the main dining room and two surcharge-free specialty restaurants. No formal nights mean the pressure to dress up for dinner is dictated by fellow passengers, not the cruise line. Regatta offers an experience that's close to luxury without being all inclusive or priced sky high. Passengers tend to be mature and well-traveled.

The 848-passenger Crystal Symphony touts "big ship" amenities such as a variety of restaurants and entertainment (including a nightclub and new "song and dance meets comedy" theater production). Its refined ambiance, exclusive-access excursions and included perks, such as wine, spirits and gratuities, attract a discerning crowd, mostly empty nesters and retirees. Crystal also stands out with its Creative Learning Institute, including classes ranging from language to filmmaking. When it's time to chow down, passengers can choose from a variety of dining options, such as Umi Uma & Sushi Bar helmed by celebrity chef Nobu Matsuhisa; Prego, Crystal's signature Italian restaurant; a nightly, pop-up Brazilian churrascaria in the buffet; and Waterside, the ship's redesigned main dining room.
