If you are interested in the Samana side of the Peninsual, I recommend that you contact Barbara Bonhomme at
barthoreal@codetel.net.do She is a realator you can trust.
If you are interested primarily in the Las Terrenas side, you may need to deal with someone else. Barbara could make a recommendation, I believe.
Also look for one of AndyB's posts and click the email or PM button underneath. He can assist you with Las Galeras.
