You have to spend 12 hours in total on a bus, but it gets you to Yosemite and back in one day and in Yosemite you see all the major sites and even get a couple of hours to walk around. Our driver Gino took excellent care of us and made sure we were able to pick up affordable lunch and dinner and crowned the great experience of the day with a special stop to view the San Francisco skyline at night before taking us back to the hotels.
This tour was amazing and our tour guide Phil kept us entertained. We would definitely recommend this tour and ask for Phil!
