1.) Before getting in a taxi that doesn’t use a meter, make sure you agree on the fare with the driver so you won’t get a surprise at the end of the ride.
2.) To avoid misunderstandings, have the hotel staff write the addresses of your destination and the hotel in the local language so you can show it to the taxi driver. Also, carry a map with the locations circled to show the driver in case they are not in a popular area.
3.) Carry bills in small denominations and change to pay; drivers often don’t carry change for large bills… or say they don’t.
