Whether they're arranging $300,000 private dinners with celebrity chefs or pop-up luxury campsites in the steppes of the northern Sahara, luxury travel agents and concierge services manage to make the impossible a reality.
Last summer, luxury concierge service Element Lifestyle secured the key to the Sistine Chapel so a New York family of six could open the doors and enjoy Michelangelo's stunning artwork alone -- an experience that cost roughly US$75,000.
On a flight to Seoul, the Asia travel specialists at Remote Lands helped a prominent Korean-American family of four buy out all 12 First Class seats -- at about $20,000 per seat -- on Korean Air so they could enjoy the cabin in private.
When a family forgot to get a Myanmar visa for one of their children, award-winning travel company Red Savannah's local fixer reportedly managed to convince the head of immigration in Yangon to approve the forms while the clients were in the air. When the travelers landed, the visa was waiting for them.
In Iceland, luxury adventure travel specialist Black Tomato made a dream proposal come true by hiding a diamond ring inside an ice cave for the bride-to-be to discover.
On another trip, Black Tomato sent a Hollywood cinematographer, who had filmed blockbusters like "Star Wars" and "Interstellar," to shoot a family on their six-week sailing odyssey through the Indonesian islands. In total, the group spent roughly US$665,000.
Super-elite travelers can afford to go anywhere and do anything, but often rely on teams of highly skilled, adaptive and creative travel experts to make it happen.
"The only reason any of these things are possible is that we've got a fantastic network of fixers around the world, who know us and the types of experiences we like to provide," Tom Marchant, co-founder of Black Tomato, tells CNN Travel.
"There is sometimes a Willy Wonka element to the way we work. Is this possible? I don't know ... Let's explore it!"
