Most Expensive Private Yacht Charter: $113,760:

The Annaliese, a $90-million superyacht owned by Greek entrepreneur Andreas Liveras, is the most expensive private yacht charter in the world, coming in at $113,760 per day. Onboard facilities help explain the price: a spa, including a marble Roman bath, saunas and steam rooms, Jacuzzis (in the spa as well as on the sun deck), a full-size movie theater, a business center and a helicopter landing pad. Custom itineraries include the Mediterranean, the Caribbean and the South Pacific. The Annaliese and her sister ship, the Alysia (which has the same daily rate), each accommodate 36 people.

Most Expensive Alaska Cruise: $47,857

A seven-night Alaskan charter cruise on the Absinthe, an expedition yacht owned by the Washington-based company Alaska Unusual, will change your definition of nature watching. The yacht, which accommodates 12 passengers and a crew of 20 (including a massage therapist and chef), passes through Frederick Sound, home of humpbacks, orcas and Dall's porpoises. A 30-foot fishing boat trails the yacht for more intimate expeditions, and an onboard Zodiac and helicopter are also available. A brand-new master stateroom, wellness center and massage center will all be unveiled this spring. A week costs $335,000 during the high season (June 20 to Sept. 1), and $285,000 the rest of the year. Rates include all expenses except gratuities.
