We have had excellent results when working with Adventure Life. We've just set up out third trip with them because the first two were great! Adventure Life has always listened, worked with us, and set up trips the way we've wanted. They've also found experiences we wouldn't have known about otherwise, that have been some of the highlights of the entire trip.
