Took hours to get to all of sites that actually were not very exciting.  First day drove 2 1/2 hours to place that was closed so 5 hours on road for nothing and it didn't get much  better.   Tried to hustle me for 385.00 extra to go to another city then wanted me and my partner to take a bus home.   You gotta be kidding me.  Then he decided that day 5 of our tour should be cut in half for a reason I do not understand.   We cut the last day out and took a $60,00 local tour of Puerto Plata that was far better than anything Tirso took us to.   He has vision problems and brings a friend to drive for him.  If your friend is attractive you may need to ask Tirso to get another driver.  If you like Lunch that is Tirso's best time of the day and ha will bring you to good restaurants.   My recomdation you will do better with local taxi drivers.
