I want to go to San Francisco and Los Angeles 17 days. How to distribute it? Where do you recommend?

There are many scenic spots in Los Angeles in these two places. You can stop by Las Vegas and the Grand Canyon. It's best to sign up for a day trip to Los Angeles and visit the scenic spots. Because you have time, Universal Studios and Disney each spend one day. You'd better sign up for a trip to Las Vegas (because the hotel is cheap and the car is chartered). Unless you drive yourself, Las Vegas and the Grand Canyon are easy to find. As long as there is GPS, the Grand Canyon will go west.

There are also many docks and scenic spots on the road from LA to SF, including Danish Village.

Fisherman's Wharf and Golden Gate Bridge must be visited. In fact, there are many scenic spots. If you want to see more, you may not be able to finish it. Specific strategies can go to "China Information Network". It's really impossible to sign up for a local tour group.
