The tour went smoothly. The accommodations were clean which was good enough and the buses were clean as well. The itinerary was great, we were able to cover a lot of ground esp. since the places to see were far from the cities.
The tour guides can do with some improvement - our tour guide for SF city tour keep saying that there's nothing to see or nothing special in there. When we went down the bus, the sites were nice - esp Civic Center. He also said that there's nothing to do in Fisherman's Wharf and that it's better to go for the cruise. While the cruise is nice, Fisherman's Wharf is big and there are a lot establishments to go and explore as well. Since we went for the cruise, we were not able to see the wharf.
Bruce Chan, our tour guide for Grand Canyon was great, though! He explained a lot of stuff and was respectful of others and recommended show (Ka) that was truly spectacular!
