I emailed Mr Sam to book an airport transfer to Twin Palms in August. He replied that we might get his friend to pick us up if he has a tour booked on that day. I see on his calender that we are the only booking that month. Is this usual, I can understand that he would want the better paying job, but we would be booking him for the airport return and for a day sightseeing. Do the other drivers recomended on TA send substitutes.
