Although a very long day - certainly worthwhile doing as the scenery is breathtaking.
But, greatly disappointed in the value for money though as we only had 2 hours in Yosemite which was definately not enough and any additional stops were incredibly rushed. This was because it took us 2 hours to get out of San Fran city centre due to the number of hotel pick ups. Equally it took ages to get back to the hotel at the end of a very long day because of all the return drop off's (would suggest that they have one central meeting point only). Be warned if you expect to take luggage on this trip, there is limited space (at one point, the driver was suggesting that luggage would have to be left behind ! - not great option if you'd booked for an overnight stay!) Potentially a great day out if it was better organised. Also, we were not able to see the giant sequois, which was why a lot of those on the trip had booked - very disappointing. Would recommend taking a warm weather proof coat as even in May when we visited, we had snow and it does get quite cold.

Fantastic trip - organised very well; informative and hospitable driver - clearly qualified with lot's of experience of taking trips out to this area. He knew how to ensure people had a great day out. Number of wineries visited was perfect - and the sample bottles at Sutter winery were excellent value for money. Yountville is a lovely en-route stop - great restaraunts. Would fully recommend this as a great day out.
