I took a 2 day tour to Yosemite and Sequoia Park. It was the worse experince ever: we spent the days on the bus, few stops in the parks of only half an hour (shameful). The guide was having an Asian accent and not always clear. In the hotel were we stayed I got bed bugs. Requested a refund for the inconvenience with pictures to prove it and they denied it with a document stating there were no bugs (after 2 weeks of the accident...of course there were nine after they cleaned the room).
