There are. I've always found it easiest and quickest to just go downtown to one of the Chinese owned grocery stores and exchange though. Any taxi can take you for a very small fee. No ID needed and you just walk up to the floor stand they sit in and hand them the money you want to exchange. Their exchange rate is nearly the same as the bank and often better than the cambios on Norman Manley Blvd. Not to mention if you want to pick up beer or liquor their prices are usually the lowest in Negril.
