We will be in San Francisco at the end of July and only have time to do a one day trip to Yosemite. I know it is not the best way to see it, but aa I am older and may not be in the area again so I would rather experience it if only for a short time than never have seen it at all. I am looking at 2 different trips. One is with San Francisco Shuttle tours where they take you to Yosemite by train and then a shuttle bus home on the return. The other is with Extranomical who has been highly rated here on TA and they do a shuttle both ways. The train ride appeals to us more, but is San Francisco Shuttle reputable and is this tour done well? Thanks for any help you can give me.
