Primarily I use Jamaican $ (the only time I use US there, is to pay my driving service from the airport and if I run out of Jamaican if I can't get to a bank in time to reload). I just got tired of being short changed with alot of my transactions when using US $ (I figured that over a typical 10 day trip that could be a couple of hundred US dollars, which is alot of Red Stripes!!! )
