Hi there,
Do you mean the Donald Sangster International Airport in Montego Bay or Kingston's airport? If so, the Donald Sangster International Airport in Montego Bay is around two hours drive to
Negril. If you are referring to Kingston's airport then, you are looking at a four hour drive.
Car rental is usually cheapest when you book it though your holiday package, otherwise you are looking at around $40 a day.
Traveling by bus it's one of the cheapest and fun way to
get around and explore Jamaica. They go everywhere and you can flag them down and get off anywhere.
Hope this helps
