Planning your first cruise can feel like an overwhelming undertaking. There are indeed so many choices, from "party boats" in the Caribbean and luxury yachts in the Mediterranean to river cruises in Asia and expedition ships in Antarctica. You need to put some careful thought into just what kind of traveler you are, and which type of cruise vacation you really want, while also factoring in such practicalities as budget, the departure port and the length of the trip.

  1. Carnival Cruise Line – Best For Value Hunters

Carnival is the line for "every cruiser," appealing to a broad spectrum of vacationers who share one common trait: They all want a super-fun escape without going bankrupt. Cruises typically start around a reasonable $80 per person, per night, and can be nabbed for lower still with promotional fares. Carnival keeps its cabins simple, with plenty of standard insides and outsides, and does not go overboard with fee-extra venues onboard (access to specialty dining venues like Guy's Burger Joint, Serenity adults-only retreats and Punchline Comedy Club shows, for instance, are all free of charge). For the best budget rates, avoid holiday periods.

  1. Regent Seven Seas Cruises – Best For Luxury Seekers

Regent Seven Seas is arguably the most inclusive of the biggest luxury brands. Its fares include all-suite accommodations (98 percent come with balconies), meals in main and specialty dining venues, pre- and post-cruise tours and hotel stays, gratuities, shore excursions and beverages from liquor to sodas (in your suite, at dinner or in the ships' public areas). The ships are on the larger size for luxury, carrying 490 to 750 passengers each -- small enough to create a social onboard atmosphere without the crowds of a big ship, but large enough to offer spacious cabins and enough dining and entertainment venues to prevent boredom. Luxury touches abound, whether it be a butler in your penthouse suite or exclusive premium bath amenities designed by the L'Occitane line. The 750-passenger Seven Seas Explorer has over-the-top suites and the highest staff-to-passenger ratios in the industry. Wherever in the world you choose to sail, you will be truly pampered.

For its youth programs, Royal Caribbean wisely splits up tweens and teens into their appropriate age groups. It also treats the underage crowd like mini-adults with such sophisticated amenities as spa treatments designed especially for the primping generation and their adolescent needs; DJ lessons; teens-only casino nights; backstage tours of the ship; and no-elders-allowed lounges where they can dance, drink mock tails and socialize with their new pals until past their parents' bedtimes. The packed schedule, overseen by an attentive crew, lets parents enjoy their own downtime without worrying about their charges growing bored and antsy.

The cruise line also fills its ships with its signature characters, such as Mickey, Goofy, Cinderella and her princess pals, who engage youngsters at planned events and spontaneous encounters. Its expansive play areas are themed after popular Disney, Pixar, Star Wars and Marvel movies, with plenty of high-tech games and interactive (and often educational) programming. Cabins and dining establishments are tailored for families with small children.

  1. Oceania Cruise – Best For Foodies

The fact that Oceania has famous French chef Jacques Pepin as its executive culinary director speaks volumes about its dedication to fine onboard dining. The main dining rooms offer high-quality fare in an open-seating plan, and even the buffets and poolside grill fare refuse to disappoint. Lobsters come sourced from the line's own Maine lobster farm, and its beef is dry-aged for 28 days in Oceania's aging facility. Specialty venues are all fee-free (minus special wine-pairing menus), and range from the Asian-style Red Ginger to Italian Toscana and French bistro Jacques. And if eating mouth-watering cuisine isn't enough, you can learn to prepare it yourself with classes in the Culinary Center.

  1. Norwegian Cruise Line – Best For Entertainment Enthusiasts

All Norwegian ships offer musical revues, comedy shows, live music and guest performers, but the line really shines with its newest ships: Norwegian Escape, Norwegian Epic, Norwegian Breakaway and Norwegian Getaway.
