For those who have the money, travel is often luxurious, over-the-top and outlandish. Travel agents spoke to Condé Nast Traveler about the most expensive, outrageous trips they have planned.

1) Cost: $2.5 Million: A Los Angeles man threw a birthday party for his wife and 30 of her friends, in which 20 vintage cars from Europe were imported to Provence for a road rally through the Bandol wine region. During the 90-minute race, the road was closed off -- and at one of the pit stops, one of the girls' favorite Los Angeles chefs served snacks. Also included in this package is a six-night sailing on a luxury cruise ship and a cooking lesson with a six-star Michelin chef.

2) Cost: $17,000: One traveler from Istanbul who wanted to visit Troy at the last minute insisted on a twin-engine helicopter for the trip. The tour, which included two pilots and a noted historian, lasted just a few hours.

-Kevan Cowie, Exeter International (800-633-1008)

3) Cost: $25,000: Justin Bieber brings a girl onstage at every concert, and someone paid $25,000 for his daughter to be chosen by the star. Another couple paid close to $19,000 for two-day trip to D.C. for Obama's inauguration and inaugural ball.

4) Cost: $1 Million: Six Russian parliament members, their wives and adult children had planned a vacation to Canada, where they planned to go to Canada for fishing, hunting and one stop for plastic surgery. Unfortunately, they had to cancel the trip because of visa setbacks.

5) Cost: $1 Million: During a three-day trip to Ireland, one family had a Celtic village, along with thatched-roof roundhouses and silversmiths, constructed at Lismore Castle. Jugglers, fiddle players, a sword fight and a private fireworks show entertained the vacationers.

6) Cost: $800,000: One Russian tycoon took seven employees and their sons on a 10-day trip in Mexico. They flew from Moscow to Chiapas in the client's private 747, rented fifteen 4x4s directly from the owners (at $10,000 apiece), hired local police and private security to supervise the entire trip, and imported groceries from across the globe.

7) Cost: $800,000: For a 50th birthday party, one Canadian woman surprised her husband with a trip to Brazil. The couple and 30 guests enjoyed dinner on Sugarloaf Mountain, and joined the winner's parade at the Brazilian Carnaval.
