I am coming to Puerto Plata the time from 11/25 - 11/30, and I would like to know the cheapest way to get from the SANTIAGO airport to the Riu Merengue in Puerto Plata. I don't speak Spanish, and Caribe Tours and Metro Tours operators don't speak English. I would like to ride the bus, I heard it's really cheap. What is the best way to arrange a way for me and my husband to the Riu Merengue without knowing Spanish? Are there English signs posted in the Santiago Airport?
