LA TORTUGA VERDE EL CUCO
You can check it out here at Hostelworld
The sweet spot Harry carved out for us to visit is right on the beach. It has all the relaxing amenities one could hope for in a vacation spot. You don't have to carry a dime as the staff keeps perfect lists of meals, beers and ice cream, boat rides etc. and tally's it up at the end of your stay. I kept track of everything myself and they were incredibly accurate with the bill.
Get a huge group of friends together and book some vans, then try to organize an exodus. We managed to cram all the people and luggage into two of these little Toyota diesels. It naturally separated into Stinky and sweet, Guys and girls respectively. I can say from being in the Guys van that is was a hell of a fun trip to our next destination - El Tunco.
