Happy Gringo were fantastic to book through for our galapagos trip. Initially we were pursuing a standard class boat, and for whatever reason this deal fell through. However the guys managed to reverse this disappointment by finding us a place on a superior class of boat, the Fragata, for the same price! This turned out to be a great move as I think the standard class facilities, though budget - minded, really wouldn't have been the nicest of experiences.
Had an amazing trip due to great work by guys at happy Gringo, go with them 100%!
