I heard on another board that the cost to parasail in Costa Maya is 60/pp for 15 minutes and that's in the village of Majahual (about a 20 min walk from the pier).....
Would love to do it but I'm afraid of heights and our 10 yr old daughter wouldn't go for it! LOL....but what we are doing in Costa Maya is delivering 2 backpacks full of school supplies to the local school there......
