The currency used in Montego Bay is the Jamaican dollar. You’re most likely to get the best deal if you exchange your holiday money before you go; just pop into any branch of Thomas Cook or buy online. Or, if you like the idea of added flexibility and security for your money, you’ll love the Thomas Cook Cash Passport. You can exchange your pounds for Jamaican dollars in resort too, where there are also ATMs if you’d prefer to withdraw cash straight from your account.
