Airport/El Catey/Samana?

I have been working this problem pretty hard recently. During the day, you can hail a gua gua to LT on the highway. The best option for late night is to make a sign. Show it in the boarding area, on the plane, and in the arrival area. Someone will be coming here, and offer you a ride.

My friend arrived Sunday night and found that everyone on the plane had transfer arrangements, so was shut out of any ride sharing. He ended up getting a taxi to a hotel a mile away that charges 1200 pesos a night, so he could wait for the inexpensive gua gua to Las Terrenas in the morning.

I think the charge is about right for the distance. Not that I agree with it, but that is what is charged anywhere else. You can maybe try to get it for 50 USD. If you add the cost of a hotel to stay overnight and a guagua the next day, plus the time, maybe it's not as much as it looks.
