>>-We would like to hit Vegas, Golden Gate Bridge, Grand Canyon, Yellowstone, but also would love to see the wonderful California beaches, and the many attractions there.<<
I you must have meant "Yosemite" and not "Yellowstone" because Yellowstone National Park is a two day drive from California. It is in Wyoming.
Even so, if you try to do Las Vegas, the Grand Canyon, San Francisco, Yosemite and beaches in 7 days, you will spend most of your time traveling between them, rather than visiting them.
I would get a good map and then read the forums here for your destinations to make a sensible decision about what is possible. Perhaps you are not aware that we are in the vast West, where things are not as close to each other as they are in the East.
I hope the seven days does not include travel time from your home, or the situation is even less possible.
