I've only ever used US dollar in the caribbean & have never given a thought to what the local currencies might be. One oddity is the Dutch Antillies (St Marteen etc) where they also accept the Euro!!
We are not sure what the other countries are but the answer is the US dollar for certain... Ask for US dollars in return otherwise you could end up with a lot of small change you can't use. The Barbadian dollar is normally half the value of the US dollar so study your change. ...... Neil.
Yes the $ is widely used in The Carribean but try to pay the exact amount otherwise you may get change in that particular countries currency.
Does anyone know if P&O have days where future cruise passengers can go onboard the ship the have booked their cruise on (i.e Ventura) when in port to have a look around and also how much is this and is anything included like lunch?
