Maybe check with your bank first a see what kind of rate they could give. I've checked every bank and Cambio in Negril over a pried of time and now I deal with FX Trader exclusivley as they seem to always have a better rate. The rate as of today at FX Trader is 1 USD = 145Ja or 1CND = 103.1Ja You can use that as a benchmark and see If your bank can do better than that, I'd change before you come down but you do have to give your bank severals days notice.
