We had an 11:00 tour scheduled and reconfirmed several times with an email confirmation. We arrived promptly at 10:50. No one was manning the booth, so we went wandering seeking someone out inside a nearby souvenir shop. We were told, at first, no, our scheduled time was noon. Then were told not busy enough so we need to go at noon. We had a tightly scheduled day, so that did not work for us. We are currently seeking money back. I realize tourism is on extremely hard times, but this is no way to gain customers back. Very disappointed.
