ATM close To Couples Negril Disperse Jamaica $$

Is there a ATM close to Couples Negril that disperses Jamaican dollars? As we are goin to bring some US cash in small denominations, but wanted to have some Jamaican $$ for off resort activities?
Does most of the bars along the 7 mile beach prefer jamaican moeny or US? Same for the vendors, US or Jamaican?

14 days to go and we are out of here!, Thanks for the help!!

there is an atm at the 7-11 type store right next to the negril airport.

Actually, they prefer US$. No need to exchange them for J$. Bring small bills though, because a lot of times in the shops, you will get your change in Jamaican.
