The savings is about $25-35 per person, not the $10 Cap is suggesting. (Taxis do not run from MBJ to Negril for $35 - more like $50-75). The bus usually stops once for beer and a bathroom break. One advantage is getting to see some of the resorts along the way that you may miss otherwise. I take the bus on the way to Negril and taxi going to the airport, many times. The extra time will only be 15 - 30 minutes, which is really no big deal.
