Looking for information regarding booking a car/taxi with an English speaking driver for half a day to drive over the road that links the Gulf of Alghero to the Gulf of Porto Conte to visit the Nuraghe Palmavera - an archeological site with two-story stone towers. Our plan is to do that in the morning and take a boat in the afternoon to their famous grotto. We are two couples on the Windstar Oct. 4 cruise from Rome to Barcelona.
