We had to wait for the 3rd bus to arrive because there were so many people in line waiting to ride the bus. We had to start out in the bottom level, but after 1 or 2 stops, we were able to move upstairs to the open top level on the 3rd row. We rode there the rest of the red tour. We didn’t have time to ride the blue tour bus, & wish we could have. We think our bus driver was Bernard, but are not sure. One thing that amazed me about all of the tours we took was the fact that few people tipped the drivers or the guides which is a shame. We recommend this tour & would do it again.
