Can you hear the ocean?

Who lives in a pineapple under the sea? You know the answer. Who travels to Mexico and stays in a shell? That could be you. 

Casa Caracol is a magnificent shell-chitecture structure available to rent on Airbnb. This one-of-a-kind property is found on Isla Mujeres, an island that's just a short ferry ride from Cancun. 

It is truly a magnificent, whimsical wonder akin to a mermaid palace if any such one was to exist. It even has shells that spurt out water as showerheads. 

If this isn't enough of a reason to get you to Isla Mujeres, perhaps the coral reef scuba and snorkeling, the Punta Sur Lighthouse, Mayan temple remains, or sanctuary of sea turtles will do it.
