Bring the majority of your spending money in cash in USD, Sterling or Euros. Generally US dollars are the easiest to exchange. If your tour remains within Southern Africa - South Africa, Namibia, Botswana, Zambia, Swaziland, Lesotho, and Mozambique - you may like to bring all your spending money in South African Rand and you can change the money before you leave your own country.
If you carry US dollar bills in East Africa please ensure they are clean, un-torn and post-2005. Anything else will incur a poor exchange rate or be refused. Your guide can advise you where it is best to change cartier replica money into the local currency on your tour and how much you are likely to require. Some tours may require you to have money already changed after arrival in the airport. Please check your tour dossier.
