How about spending "Doomsday" in Mexico this December? That's the invitation from four condo-style hotels in Playa Del Carmen, where the ancient Mayan calendar is calling for the world to end Dec. 21. Rather than taking sides, the hotels are rolling out an offer for believers and skeptics alike.

The properties -- El Taj, Porto Playa, Maya Villa and Villas Sacbe -- are offering a free night's stay Dec. 21 for guests who book a three-night minimum stay (rates from $175 a night). And if indeed the Doomsday prediction come true, the hotels cheekily state, they'll give guests double their money back. Details at condohotelsplayadelcarmen.com.

A more serious reason to visit: Playa Del Carmen will be awash in Mayan cultural celebrations -- premier Mayan sites such as Chichén Itza are nearby, too.
