Quintana Roo, Mexico has an area of 50,212 sq km and a population of about 1,135,300. Its capital is Chetumal.
Quintana Roo shares its borders with Belize and Guatemala and the Mexican states of Campeche and Yucatan; it is surrounded by the Caribbean Sea to the north and east. It has an extensive coastline along the Caribbean Sea along with tropical jungles and savannah land.
This region was dominated by the Mayans, before Spanish occupation. The population here is mainly Mestizo (mixed indigenous and foreign ancestry).
I find that vacationing here is not the same as living here. When I travel on extended vacations, I prefer to live in a place just like the local people, renting an apartment, not a vacation home. I found the local Mayan population in Playa not to be very friendly to foreigners. The typical one to two week vacation in an overpriced resort like hotel near the beach is not the same experience as living here in a typical apartment that rents for roughly $200/month. Of course if your like most visitors, you'll probably stick to friends that are also visiting. I prefer to live amongst the people to experience something new and to learn about their culture, this was not possible in PDC. Belize or Costa Rica would be a better choice, I didn't have any of these issues there.
Akumal is laid back and more private than other areas on the Caribbean coast. Great scuba diving, snorkeling and fishing on a tropical fish filled reef. Location is great base for exploring Mayan ruins, beautiful beaches and jungle adventures. Car is recommended, but bikes and golf carts are alternative transportation. Villas and a number of low-rise condos are available to rent. A handful of good restaurants are within walking distance. Two of the best thatched-roof beach bars are the meetup destinations. Nightlife is sparse, but only 30 minutes drive to Puerto Avanturas, Playa del Carmen or Tulum for wilder entertainment.
