Our driver Vidu tried hard during the day, drove us safe, and was very enthusiastic. However, I felt that the latter part of the tour (in Galle and the stilts fishing, the beach) was a bit rushed. So I suggest spending lesser time in the earlier stops (I would say the Turtle Sanctuary - maybe even skip it) so you can spend more time in Galle Fort, one of the beaches (where you can feed Turtles in the ocean) or even two, and also maybe wait for the sun set if the stils fishermen if time permits.
