Check out the world's most expensive holiday - a $1million trip complete with a private Caribbean island, unlimited Dom Perignon champagne and a chest of gold. The one-week break includes return private flights from America to Calala Island off the coast of Nicaragua. The bumper price gets four luxurious beach-front villas for 10 people on the secluded palm-tree-lined Caribbean paradise. To ensure celeb-level privacy, a no-fly zone will be in place for the entire break and visitors will be looked after by 25 staff.
