Got Titanic fever? Try a cruise, show, dinner

— -- If you haven't already booked passage on the Titanic Memorial Cruise, which will retrace the route of the ill-fated luxury liner, you've missed the boat. The 12-night Southampton-New York sailing commanding fares of up to $16,000 sold out 18 months ago.

A Groupon deal hawking a 13-day voyage that will visit the 2½-mile-deep wreckage via Mir submersible for $12,500 (that's 79% off the $59,680 asking price!) sold in minutes this month.

Still, there are plenty of other opportunities to catch Titanic fever in the run-up to the 100th anniversary of the sinking of the unsinkable ship on April 14-15. From dinners that re-create the final night's menu, to a line of Titanic-inspired jewelry, to the opening of two major Titanic-themed museums and musical tributes at others, the centennial of the world's most famous sea disaster has sparked a marketing frenzy.

There's still availability on an eight-night Titanic Anniversary Cruise departing New York on April 10. Like the Titanic Memorial Cruise sailing in the opposite direction, the voyages are timed to reach the wreck site in the North Atlantic on April 14 and 15, when there'll be a 2:20 a.m. memorial service aboard both vessels.

A number of descendants of those who perished will be on board both cruises, which were organized by a British travel agency. Other passengers are longtime Titanic "enthusiasts," says agency owner Miles Morgan. Titanic's place in recent popular culture also has stoked demand.

"You've got people who are new to Titanic. They played the Celine Dion song at their wedding," he says.

"And then there are the compulsive cruisers. They've done everything else and are looking for something different."

Among land-based Titanic-centric doings:

•Titanic Belfast, a waterfront development, opens in Northern Ireland March 31 near the spot where the liner was constructed. Its centerpiece is a dramatic building covered in metal shards that's designed to resemble the ocean liner's hull. Inside are nine interactive galleries. A nearby trail traces Belfast's industrial past. Titanicbelfast.com

•Titanic claimed the lives of 549 Southampton, United Kingdom, residents, most of them Merchant Navy crew. Sea City Museum, opening in April, will spotlight the lives of Merchant Navy members. Its first temporary exhibit, Titanic, the Legend, will examine why the disaster is the object of such enduring fascination. Seacity.co.uk

•The Titanic Museum Attractions in Branson, Mo., and Pigeon Forge, Tenn., will stage a musical tribute dubbed A Night to Remember on April 14, culminating in the sounding of distress signals and the lighting of an eternal flame. The ship-shaped museums re-create interiors from Titanic and house hundreds of artifacts collected from the vessel's debris field. Tickets to the show: $45. titanicpigeonforge.com and titanicbranson.com

•Halifax, Nova Scotia's connection to the doomed liner was a matter of fate. Titanic sank 700 nautical miles east of there, but because it was the closest city with good rail connections to America, it became the hub for recovery operations.
