We are making a trip to Roatan in February and plan to spend 3 nights in Utila. Our flight to / from the U.S. is through the Roatan airport. What's the best way to travel from Roatan to Utila and back? I see that there is a catamaran ferry that goes direct between the islands and then a ferry (or airplane) that goes to the mainland and back out to the islands. What is recommended?
