As others have said, there are a number of cambios in Negril, aside from the ones at the roundabout. Personally, I like the Banmark on the West End Rd. There is usually no line and I have never had a hassle there. I know it's out of the way for people staying on the beach, but you can pair it with a trip to Negril Escape for cliff jumping, Bella Donna's for pizza, Quality & Faye's gift shop or any number of cool places within walking distance.
