The guide was very passionate and super nice. He taught us a lot, a lot of stories and all with humor. The bus ride is very long even if the guide does everything to make it pleasant: stories, culture, music, jokes and even movies. Otherwise, the places chosen are truly amazing. Yosemite Park is unique and I think this tour really captures all of its splendor. My only regret that I didn't have time to stop more (but hey, it's the time to not come home too late). What I liked the most was the view from the tunnel as well as the view from the bottom of the valley (last stop before departure). Also, the place for lunch in front of the waterfalls is just unique. As for the agency that takes charge, they are top, available and really take you to the hotel and bring you back there: which is comfortable anyway.
