Good advice from dan. In addition to what he said about taxis, the hotel I stayed in actually wrote down the number of the taxis they called up for me (there was a nice person outside the door that would wave up a taxi for me whenever I needed one). Then, if I got ripped off by the taxi driver, the hotel would take charge and handle it as they had the number. Got ripped off only once though, and that was not while driving from the hotel - in any case it wasn't too much money.
