St. Croix at $253 RT

There's only one creature with the grace and agility to keep a crowd on the edge of their seats.

Meet... the noble hermit crab.

These speed demons can be claimed and named for $2. Released from a bucket by the sound of a kazoo, they race for the finish line with the most determination you can expect from a crustacean. If your sponsored crab crosses first, you can win anything from jewelry to tours to rum. 

The crabs are cared for by a local couple that hosts the races twice a week and kids usually get special treats at the end. So everybody wins! 

P.S. Dates are a bit scarce on this one so book quickly and use the example links below. I also spotted two dates with American at $237 RT (here and here) that could disappear at any moment.

Best of luck :-)
