Dear M.S, Normally, if the weather condition is good, the tour will still go to Yosemite in mid December. But if the weather condition is bad like it is snowing, the tour will go to 17 miles drive instead. So basically it depends on the weather. Thank you! Best Regards, Natsu Customer Service Rep

Dear Ben, Yes, your 8:45pm flight will be fine. We recommend booking a domestic flight departing past 8:30pm as the tour guide will generally arrange for the drop off out to LAX on the last day at around 7:30 pm. Best Regards, Alex Customer Service Rep

Dear Christina, Thanks for your inquiry. Tour code 2-5602 will pass by some world famous IT company's headquarters during this tour (such as Apple, Microsoft, Google and so on).
