Thank you all for the info, I was hoping that Metro or Caribe was a possibility. We will be carying 3 bags.
Transportes Papagayo 809-749-6415 leaves Puerto Plata Hospital around 6:45am once a day for Samana. They stop in front of Janet's but will stop anywhere in Cabarete/Sosua if you call them. I was told they go through Cabarete at about 7:15am. To be safe, I would be in the sub stop at 7am. They stated it is a blue bus (not purple) but I wouldn't trust that what we may consider purple is shade of blue for Dominicans. They will stop at the airport entrance for you.
