AS the 2013 season gets under way, cruise trends are shaping up to include a bigger focus on multi-generational groups, more specialty food offerings and continued efforts to wow passengers with new onboard firsts like an aquapark, a glass walkway and a vertical garden.

Here are some details on what's new in cruising.

The new it ships

CruiseCritic.com editor Carolyn Spencer Brown says two of the hottest new ships debuting in 2013 are the Norwegian Breakaway, which will be the largest ship ever to homeport year-round in New York City beginning in May, and Princess Cruises' Royal Princess, launching in June.

The Breakaway's exterior features the unmistakable pop art of Peter Max, with Lady Liberty's face and a city skyline anchoring the brightly colored design. Onboard the ship offers an open-air 400-meter boardwalk and an aquapark, including five multi-story water slides and a double freefall slide where the floor drops away. The ship will carry 4,028 guests and will sail weeklong cruises to Bermuda through October 6.

The Royal Princess will carry 3,600 passengers and will feature a jogging track and the SeaWalk, a glass-bottom walkway extending 8.5 meters beyond the edge of the ship and 39 meters above the ocean. One part of the ship, The Sanctuary, is described as a "signature haven just for adults," with private cabanas and steward service for light fare and drinks.

Its maiden voyage will begin in Southampton, England, and head for Spain and Portugal, followed by trips to the Mediterranean and Caribbean. It calls on Fort Lauderdale, Florida, in October.

"The important thing about these two ships is what they say about cruising, which used to be you were outside during the day and at night you got dressed up and had dinner and went to the theater," says Spencer Brown.

"Both ships reflect the new trend of being outside all the time with outdoor restaurants, more on-deck seating and other reasons for you to be outside."

New attractions and activities

Today's cruise ships offer everything from skating rinks to planetariums to climbing walls, but the new attractions and activities just keep coming. Among the latest:

? Crystal Symphony debuted in September with a vertical garden, which is a plant-covered freestanding living wall, 2.4 meters high.

? The MSC Preziosa ship, debuting in March, will feature what's being called the longest single-rider water slide at sea - 120 meters.

? On the Celebrity Reflection, an all-glass shower extends over the edge of the ship with a wraparound verandah and special glass so you can see out, but not in.

? On Cunard's Queen Mary 2, Queen Victoria and Queen Elizabeth ships, passengers can take "back of the house" tours and visit everything from the engine room to backstage theater areas to the kitchen galley and the recycling facility.

? Carnival Cruise Lines offer TV-quality game shows at sea with passengers as participants, along with 3-D movies in theaters equipped with motion seats and special effects like wind and water.

? Holland America Line has a programming partnership with "Dancing with the Stars" while Celebrity is partnering with Zumba for fitness workouts and pool parties.

? Theme cruises woo fans of everything from country music to sports by hosting performances and celebrities onboard. NFL coach Don Shula and Miami Dolphins Hall of Famer Larry Csonka will be on a Crystal Serenity cruise this summer.

Specialty food

It seems like every cruise line is upscaling and expanding food options. Disney Dream and Disney Fantasy in October began offering a US$50 per person Champagne brunch at Remy, Disney Cruise Line's adult-only restaurant named after the character from the animated film "Ratatouille," with dishes created by the French Michelin-starred chef Arnaud Lallement. The Norwegian Breakaway will have everything from a churrascaria - Brazilian-style steakhouse - to separate bars for Asian noodles, gelato and raw shellfish. On MSC's forthcoming Preziosa ship, there will be an Eataly Restaurant modeled on the Manhattan Italian gourmet food mall.

Celebrity chef Jacques Pepin has served as Oceania Cruises' executive culinary director for nine years, and this September, he'll be a guest on Oceania's Riviera ship, doing a cooking demonstration, Q&A and meet-and-greets with guests at his namesake onboard restaurant, Jacques, and the ship's culinary center.

But there may be a downside to some of the new food offerings. Arnold Boris, editor-in-chief of Cruise Gourmet, says he has found that as specialty food options with extra fees increase, basics that used to be offered for free decrease. "It's all unbundled now," he says.

Spencer Brown agrees: "The quality of the main dining room has gone downhill while they've raised the prices to get into these alternative restaurants."

The unbundling trend is seen in other areas as well, with mass market lines keeping fares low but charging extra for various onboard activities. Ironically, the opposite is happening on luxury lines, where "they don't want to lower (ticket) prices because it doesn't look good, but they're throwing everything in for free. Luxury is the best value it's ever been," Spencer Brown says.

Ship revitalization

Fewer cruise lines are building brand-new ships, but many are doing intensive renovations on existing vessels. Some of these renovations involve adding new spaces to accommodate a fast-growing segment: multi-generational groups. Cruises are being marketed as the perfect vacation for grandparents, parents and kids to take together because they can pursue different activities onboard, then have a meal or shore excursion together.

On Norwegian, for example, between 15 and 20 percent of guests on any cruise are part of a multi-generational group, according to spokeswoman Vanessa Lane. "Families are the second-largest cruising segment, only behind the 55-plus age group," she says.

More than half of Carnival bookings involve more than one state room, no doubt many booked by family groups.

To accommodate the diverse needs of old and young, ships are expanding areas for youth activities while at the same time creating more adult-only pools and quiet areas where passengers can nap, sun, or read a book. Carnival ships have "Serenity Spaces." Norwegian ships offer exclusive suite areas with key-card access and private courtyards called The Haven; they're not adult-only but they are designed to be quieter than other parts of the ship.

Carnival ships increasingly offer observation areas next to youth play areas where parents and grandparents can watch their kids play. "My mom's not going to play basketball with her grandson but she sure wants to take pictures," says Jim Berra, Carnival Cruise Line's chief marketing officer.
