So I'm reading Anthony Bourdain's The Nasty Bits and one chapter is his experience on board The World for five days. (He decided he was going to do all of his own cooking, so hardly a mention of the ship's restaurants' meals.)

Anyway, I decided to take a peek at ResidenSea's website tonight out of sheer curiosity. Purchase prices are listed from $825k to $7.3m. Annual fees range from $88k to $554k. Rent for short stays (min 6 days) is $1,200 to $4,200 per night.
