David Copperfield may be capable of some of the greatest magic tricks the world has ever seen, but even he couldn't conjure himself a tropical island out of thin air. He had to pay for it, just like everybody else does. He has gone a little further than the other people we've discussed so far though - he didn't buy one Bahamian island, he bought four.
Nobody knows for sure how much Copperfield paid for the islands - so perhaps we can't completely rule out magic after all - but we can tell you how much other people pay for the privilege of enjoying them. Copperfield converted Musha Cay - the largest of his islands - into a guest resort, keeping the other three for private accommodation. Five-star service awaits visitors, including a private chef and butler service. That's probably the least you should expect for $37,500 per night.
