We decided to go to San Francisco for 5 nights and were planning on renting a car. Car was going to be cheap..$65 ai for 5 nights...but parking is RIDICULOUS! It was going to cost $40-$50 per day just to park at the hotels we were staying at. Enter Zipcar. Turns out there are Zipcar locations everywhere in San Fran including right next to our hotel. Zipcar's rent from $7 an hour. It's perfect. Rent the zip car for a few hours during the day to cruise around the city and then return it back to the garage by the hotel. And they include gas and insurance. There is a $50 fee to join and $25 app fee unless you work for a university or are a student. Even sweeter...I found a $40 driving credit code. HVEZFEWX I figure I'm saving well over $250 on the car cost.
