The guide was excellent but tour company extremely disorganized
I reserved this excursion and money was immediately taken on my Visa card. We were told it might take 48 hours to receive the confirmations. After a week I wrote again and they relied immediately they would get back to us in 24 hours. Two days later I enquired again. I received the tickets a few minutes later.
We were to meet at 10:30 a red or green person. At 10:35 he arrived, no correct color, but he had to wait for Florence to arrive with tickets. When I told her I was not impressed she was surprised, I was told as she was only 12 minutes late....
However, tour guide was great and we enjoyed the tour. He spent more than the two hours we scheduled. All well in the end. But I would not use this company again.
