The driver was good. The pricing was outrageous. At least double the rate of that posted at the park.
$199 plus tip ($240 total) through Viator for 30 minutes. The posted rate at the park is about $60 for 20 minutes, then $20 for each additional 10 mins. The charge would have been $80, plus I would have tipped $20, for a total of $100.
Through Viator, it was $240.
Never again.
