This tour was 3 hours. We stopped 3 times. Once at an ice cream stop, a lookout and a historic cabin community. The rest of the time, we drove around. There were 8 of us so I was automatically charged $136 gratuity. This is on top of the $80+ I paid for each person. Looking back, I would have drove my family myself, saved this money and have seen some sites like Clingman's Dome.
