lots of good advice given. good to know that the dollar is widely accepted, especially in the bahamas
. in the bahamas
the us dollar and bahamian dollar are 'on par' (the bahamian national bank guarantees an equal exchange rate) and used interchangeably. it's a little weird but not uncommon to pay for something, or receive change for a purchase
, in a combination of us and bahamian money.
we keep cash on the boat, well hidden. we use one debit card and one credit card, although we have several more. the debit card is on an account in the usa which is topped up monthly by uncle sam (social security). the credit card is on an account in the usa that has the monthly minimum payment amount automatically paid to it every month, so i don't have to worry if i miss a monthly payment. i can pay more if i want to.
try to keep track of your accounts by internet whenever possible. also, be sure to notify your cardholder that you will be traveling. once we didn't and they nearly closed our account for suspected fraud when they had charges coming in from foreign countries and couldn't reach us on the phone
if you're only traveling in the usa then it's no different on the boat than it is on land.
travelers checks, by the way, have pretty much gone the way of the dodo bird....
