I will be in the DR from July 14 for three weeks. I do not plan on renting a car since that is the advice I received from this page. I will be staying at Casa Linda along with my son and grandson. Any advice on transportation to Sousa and the other towns will be appreciated. Also, any idea as to the cost of having a car/driver for a day that could show us the various "must see" locations like the falls, etc. Thanks for your time!
