We waited at a marked stop for over an hour, as the brochure told us we could get on anywhere. Finally took a taxi ($15) to a downtown stop, where we were told that stop no longer existed, even though it was on the map. Told as we had booked through a third party vender, nothing they could do. Finally they agreed we could have a ticket for the next day. We wasted a half-day of a 5-day vacation. When we did take the tour, it was disappointing. Very little information about the sights, much less than the 2-hours we’d booked for. A complete waste of time and money.
