He will pick you up at airport and take you to La Manzanilla for 3000
pesos. He has a large modern van and can easily take you family and luggage. I have used his service and found him an excellent driver, very personable and speaks reasonable english.
There are slightly cheaper options but could not take a larger group plus luggage.
