The Caribbean remains a top destination among cruise passengers, and more are bringing their children along for the journey, according to a survey by the Cruise Lines International Association.

Cruise experts also say that in response to rising fuel costs, cruise lines are increasing surcharges and changing their itineraries. Some are skipping Aruba, once a popular port in the southern Caribbean, because of the extra fuel it takes to get there.

"You're seeing a lot less of the real exotic types of itineraries that require more sea time, because it's so expensive," said Carolyn Spencer Brown, editor in chief of CruiseCritic.com.

Consumer interest in cruising remains strong, according to CLIA, a marketing arm for several of the major lines. The survey found that 55 percent of vacationers who have never taken a cruise intend to do so in the next three years.

But many cruisers are watching their budgets, said Brown, cutting back on onboard spending, planning independent short excursions and choosing a cruise near a home port to avoid having to fly to meet the ship.

That means the Caribbean is rebounding and the Mediterranean is losing out, Brown said. So much that Carnival is pulling the Freedom from its previously announced 2009 summer itineraries in the Mediterranean and positioning it year-round in the Caribbean.

The Caribbean is traditionally cheaper than other cruises, because it is a year-round destination and many passengers don't have to travel far to catch the ship. Other cruise regions are seasonal: Canada/New England and Alaska are only accessible via cruise ship in warm months, Brown noted.

"With the Caribbean, one of the biggest advantages is there's simply more choice and it's a much more flexible option," said Brown, who added that cruisers will have the most choices in terms of a ship from the winter holidays to mid-April. "During times of the year when there's more variety, pricing will be more competitive as well."

While vacationers, including cruisers, generally travel in pairs, family travel is exploding, Brown said. In 2008, 25 percent of cruisers traveled with kids under age 18, compared to 13 percent in 2002, according to CLIA.

The increase may be responsible for bringing the median age of a cruiser down to 46 in 2008 from 49 in 2006.

There has been a rise in family vacations overall since the Sept. 11 terrorist attacks, said CLIA spokesman Bob Sharak.

Brown compares today's cruises to camps -- ships retrofitted with science labs, teen lounges with video games, plasma TVs and dance floors. There's rock climbing, surfing and miniature golf. Some cruises even offer teens their own place to sunbathe, or special mom-and-teen spa packages.

Cruises are also a superior economic value for families, said Heidi Allison-Shane of CruiseCompete.com. She added that her college-age children have run up thousands in room-service bills on non-cruise vacations.

"You can have as much as you want to eat," she said. "You can have your children with you and yet everyone has their own activity."

Cruise lines are also increasingly marketing to other countries, said Brown, so some ships have more of an international mix among the guests on board.

Even with no clear end in sight to rising gas prices, cruising is not expected to decline, said Allison-Shane. The overall satisfaction ratings for cruises are high: 95 percent of all cruisers rate their experience as satisfying and more than three-fourths of past cruisers plan to take another cruise within three years.

Brown says some of the most exciting cruise ships have yet to set sail. The new Celebrity Solstice has a freshly manicured lawn on the highest deck and Royal Caribbean's Oasis of the Seas will be the largest cruise ship in the world when it launches next year.
