Phnom Penh, Cambodia

Perhaps because of the heat, Phnom Penh is more laid back than other Asian megalopolises. People are friendly, especially taxi drivers, who know just enough English to demand that they stick with you all day and become your personal tour guide. Say no, and their moods darken. Suddenly, going anywhere becomes impossible. An alternative: Transportation is so cheap in Cambodia that you may as well just get a credible driver for the full day. Taxi Vantha, costs just $25 per day, and is well worth it to make the most of your business trip or tourism time. A ride to the airport when you leave: just $7.
