1. We will buy pass at the first park we visit.
2. We are allowing approx $210 for fuel (Ford Fusion)
3. We paid for Alcatraz boat trip ✔️

Now...
Bicycle rental. We want to do this in San Francisco to go through the bridge.
Grand Canyon also offers this, is this better option than walking/car? We arrive mid day to Grand Canyon (approx) and leave the following afternoon.
