It is always prudent to carry a little foreign cash, however, in case you cannot find an ATM or bank office nearby. You can always change cash at the hotel, though the commission will be high. Make sure you have enough of the national currency when you plan to visit local markets and shops.

Tipping

When a gratuity is not included in your bill, which is usually the case, 10% is customary. If service is outstanding, you could go as high as 15%. With taxi drivers, you usually just round up the sum if you have been happy with the ride or for the sake of convenience.
