PORT CANAVERAL, Fla. | The christening ceremony, complete with elaborate musical number, fireworks and a 16-foot champagne bottle, was typical in-your-face Disney. The best attributes of the company’s newest cruise ship, though, aren’t quite so over-the-top.

Oh, the 4,000-passenger Disney Dream certainly has some wows, such as a 765-foot “water coaster” whose clear tubes wind and twist above the highest decks, but the Disney whimsy here is more understated than you might expect. Art deco interiors and other classic touches in common areas hark back to a time when only the very wealthy could afford to sail on ocean liners. From the atrium’s massive chandelier to the plush theater, it’s a grand display.

“The goal was to create an experience for all generations — for people who come with grandparents and great-grandparents, for people who come without children,” Disney CEO Bob Iger said on one of the Dream’s first trips out of Port Canaveral. “I think everybody takes out of it what they want, but I think we’re providing a tremendous amount of surprise, too.”

Still, the Disney brand is never far away. Blankets, bedside light fixtures and bath towels bear silhouettes of Mickey Mouse. The 150 inside staterooms, typically the cheapest accommodations on a ship because they lack windows, are equipped with “virtual portholes” providing live views outside the ship. The innovative video feed is embellished by the occasional appearance of Disney characters.

A technology-filled children’s area called the Oceaneer Club promises to keep kids stimulated while parents relax by a quiet pool or pull up a bar stool in one of the chic clubs in an adults-only area called The District. The Oceaneer Club’s 103-inch plasma TV screen shows movies but also offers interactions with an animated character, the surfer-dude sea turtle Crush from “Finding Nemo.” In a neat show of Disney innovation, Crush appears to hold spontaneous conversations with guests, responding appropriately to whatever they might say.

Crush is also the star of an interactive experience in an assigned-seat dinner restaurant called the Animator’s Palate, working the room on huge video screens with other “Nemo” characters and marveling at diners in the “human tank.” In 22 other places around the Dream, “enchanted art” on walls comes alive when guests approach, thanks to nifty video techniques and motion detectors.

“Technology is an enabler throughout the entire ship,” Disney Cruise Line president Karl Holz said. “It brings the ship to life in many, many different ways.”

The backdrop for an adult bar called Skyline is a huge fake window offering pictures of big-city skylines. A massive video screen over the main swimming pool shows cartoons and drives the raucous “Pirates of the Caribbean” deck party.

This ship also has more entertainment for ’tweens and teens, a demographic that wasn’t as engaged as younger kids on Disney’s other two ships, said Carolyn Spencer Brown, editor-in-chief of www.CruiseCritic.com. As a result, Brown said, Disney was losing families with kids older than 10.

The Dream carved out a larger, cooler, no-parents-allowed space connected to a private sun deck. The Oceaneer Lab is chock-full of video games and other technology.

“I think that was the one thing they really had to nail,” Brown said.

Food in family dining areas is above-average, with fancy date-night experiences available for an extra charge in ship-top French and Italian restaurants.

The Disney Dream, carrying 40 percent more passengers than either of the two existing ships in the fleet, is sailing three-, four- and five-night cruises to the Bahamas and Disney’s private island.
