This is a mixed review because there was a mix up in our reservation.
The tour itself and our guide from Sixth Sense was excellent-- definitely 5 stars for sixth sense. Only problem is we booked with a different tour Shannon Scott and when they started checking us in they said Viator is a different group but there were no other groups there so we started to get concerned and my husband started walking around to try to find someone else. When our actual guide showed up he said that Shannon Scott didn't have enough for a group that afternoon and asked him to take us so it worked out in the end and as I said the tour was very good.
However we have booked tours all over the world with Viator and never had any problem just excellent results. It would have been nice for our original tour guide to have sent us an email explaining the situation which we would have totally understood. That would have prevented a few quite unpleasant moments when we thought we were going to be abandoned and out our 50. We have always felt completely confident in booking with Viator-- and recommended you to others-- but our confidence now is just a bit shaken.
This tour was so well worth the money spent. Our guide, Lisa Marie, was so knowledgeable and enthused about the history of this intriguing place. The stories she shared were absolutely fascinating! We would do this again.
