Well worth paying the money for this trip. Brian our driver and guide was friendly from start to finish and gave us loads of interesting info about Yosemite before we got there, the documentaries he played in the van were really interesting, not to mention all the info he gave us there! Plenty of time (1 hr 40) free time to explore alone too, which was enough time to have a relaxed picnic lunch by the river and do a short trail. With Brian we saw all the main sites - three brothers, bridail falls, the Merced river, half dome, el capitan (with some climbers on!), and where Yosemite falls would be (it was dry), the sequioas were impressive and we even saw a bear on leaving! The walking was not too strenuous and the drive was not too long and had a short stop on way there and back for food, toilet etc - good back into central San Francisco at about 9pm. Absolutely loved this day, Yosemite is breathtaking.
