I always use towncar sedans with driver to and from the airport. My current rate is $60 each way including tax and built-in gratuity. Even though the tip is included in the rate, most people who use the service give the drivers a little extra. If I were to give extra, what do you think is an appropriate amount to give?

Question #2: I'm going to be using a towncar and driver for two days, 12 hours each day. The fee the company is charging me per day is $600, tip not included. How much would you tip the driver per day if he does an extremely good job?

Using these limo services may seem like an extravagance to many, but they have actually saved me money and often know more about their cities then the hotel concierge, amazing how much you can learn from airport to hotel.
