Trying to decide between shuttle (Interbus) and private transfer between Arenal(staying at Silencio del Campos)and Montezuma. Would the travel and/or route be substantially different? I.e. is there a more scenic route to be chosen if one goes by private car? Are there a lot of places one might want to stop along the way? We are two people, myself and my eleven-year-old daughter, so the cost would be substantially different, but I am willing to pay if the advantages are sufficient, as we are doing a lot of travelling. Thanks.
