Water Worlds
Owning a private island has practically become commonplace among the world's richest citizens (Think Richard Branson's Necker Island and Johnny Depp's Little Hall's Pond Cay.) But you don't have to be a billionaire to afford your own private island escape. There are a few websites that list islands for sale, such as Private Islands Inc. and Vladi Private Islands, and if you search carefully, you may find listings well below the $1 million mark.
