Our driver was on time, professional and a really nice guy. I would definitely use Viator again.
Could we have gotten there cheaper? Probably. But this service was easy, fast, comfortable and the driver was courteous. And they handled six people. So the real question is "was it worth it?" And to that I'd say, "absolutely."
Driver was parked in the wrong area ( supposed to be in valet parking but parked at the front of our hotel) delayed our trip for 20 minutes.
The driver did not speak at all throughout trip only said thank you when given a tip???
