Taxi fares in Negril are a bargain. I don't mind taking route taxis as long as it's not morning or afternoon rush hour when locals and students need the seats. Other time, drivers are happy to carry you for the 'local legal rate'. I usually charter because it's just so cheap. For instance, Margaritaville on Norman Manley to Seastar Inn deep west is about 500 dollars for two people during the day when negotiated. That ride here at home would cost 2000 dollars, maybe more. If we take route cabs we always tip the equivalent of one extra fare. You certainly don't have to do that though. Operate as you see fit and as you can afford.
