If your only worry is about a place to stay--no need for concern! The bay area has a lot of hotels, and you should not have any problems except in the landmark San Francisco hotels and some of the Carmel b&bs. (But you can always find a room somewhere in both cities.) The bigger problem is driving on the freeways--traffic can be horrendous, and in San Francisco, it's best not to drive at all.

Perhaps you can be a little more specific about your itinerary, especially the amount of time that you have, as you begin by mentioning SF but then quickly segue into the peninsula, Sunnyvale, San Jose, and Monterey, which are in many ways a world away from San Francisco. As a 20-year resident of the peninsula, I would suggest that you not plan to spend a lot of time in this non-coastal stretch between San Francisco and the Monterey Peninsula. It is a lovely place to live but not very interesting to visit. If I had limited time for tourist attractions in this part of the world, I would stick to the coast, Monterey/Big Sur, San Francisco, Napa/Sonoma.

But it really depends on what kind of experience you want. If you can be more specific about that (and about how much time you have) those of us who live here could offer more specific suggestions.
