most popular travellers' cheques used in The Gambia are Thomas
Cook (ABTA & IATA protected), and American Express Travelers'
Cheques (Amex), who both have a widespread network and fairly
efficient replacement system in place.
As a general rule you tend to get a better exchange rate when
you change cash into the local money, the Dalasi, than you would
get converting travelers' checks into cash at a bank or bureau
de change. However, if you are staying for a longer period it
is more advisable to have a mix of say 75% cash and 25%TCs. This
is for reasons of security, as they can normally be replaced within
24 hours from the time you report the loss, whereas it is a different
matter for loss of cash.
As an emergency back up do take along any debit or credit cards
as they can be used at some bank ATMs to withdraw cash. To minimise
the chances of loss do keep both cash and travellers' cheques
in your resort's in-room safe or at the reception desk's safety
deposit box. Do hold a copy of the original TC receipt,
and note down their serial numbers. This is because a few banks
will not honour your cheques without your original receipt.
