To those who've been to Barbados, what money do you take USD or Barbados Dollars... it's just I'm not sure and I can get a much better rate on USD than I can on Barbados Dollars, as I can only get the latter at the Travelex in the airport with their sucky rates and can pre-order the USD with a good rate.
USD. Pretty much everywhere accepts and uses USD (including cabs in my experience) but you may get your change back in Bajan Dollars from smaller outlets.
Thanks,
Sarah
