WORLD'S MOST EXPENSIVE VACATIONS

1. A Vacation to the Moon

Space Adventures provides the opportunity for you to blast off in a Soyuz spacecraft for a circumlunar mission. During the seven-day space flight, which reaches top speeds of 17,000 mph, you'll see stars, the illuminated far side of the moon, and the Earth from 250,000 miles away. Candidates must train for four months alongside Russian cosmonauts at the Yuri Gagarin Cosmonaut Training Center in Star City, Russia. Two seats are available for $100 million each.

2. A $1 Million Vacation

A battle is brewing for bragging rights to the most expensive vacation. The Emirates Palace resort in Abu Dhabi announced a Million Dollar Travel package that "incarnates pure opulence."Along with first-class airfare and seven nights at a giant suite at the Palace, the package includes:

Chauffeur-driven Maybach at your disposal daily during your stay in Abu Dhabi.

Daily SPA treatments.

Day trip in private jet to Iran where you'll create your own Persian carpet with the country's most-exclusive and best-renowned hand-maker. Day trip to Bahrain in private jet for "a pearl deep sea experience," with the pearl hand-designed settings.

The Emirates is hoping the trip gets it a slot in the Guinness Book of World Records. But it turns out that Leading Hotels of the World has its own ode to opulence. Its $1 million Around the World in 80 Ways trip, which plays off the storied journey of Phileas Fogg, lets travelers recreate the 19th-century around-the-world fantasy experience with 21st-century comfort and flair.
