I ended up meeting and talking with the owner Marco Antonio. He gave me some great tips on things to do around the area. Namely, visit a turtle conservation project and a biosphere park called El Cielo (The Heaven).
Kemp's Ridley and Green turtles, I believe that both are endangered species.
Afterwards, I tried unsuccessfully to use an ATM to get some Pesos. The attendant said that they only had a relationship with six banks. Oh well.
Off to El Cielo.
