San Francisco, California
My wife and I spent two nights in San Francisco for two nights. During which time we chose not to have a rental car because of the expense to park at any downtown hotel (typically $50 per night) as well as just finding a parking place most anywhere ...not easy! If you are going to visit San Francisco for a two or more days ...Hop-on Hop-off Tours is the way to go! It's relaxing, informative, easy and worth every penny! We loved having the freedom to tour the Bay area at our pace without the headache of driving in bumper to bumper traffic and looking for a place to park.
