Money: The official unit of currency is the Tanzanian shilling (TZS), divided into 100 cents. The tourism industry prices everything in US Dollars and they are the preferred unit of currency. Major currencies can be exchanged in the larger towns. Foreign exchange bureaux in the main towns usually offer a better rate on travellers cheques than do the banks. ATMs are available in major cities only. Major lodges, some hotels and travel agents in urban areas accept credit cards, but these should not be relied on and can incur a 10% surcharge. Visitors must pay a $50 airport tax on arrival and a $30 tax on departure.
