Why the rental?Taxi is easier,may even cost less. Being from Chicago,you are probably used to aggressive driving,but it is a lot different on the rock... We are going to Negril,then Treasure beach. South coast is great.Very laid back,not touristy,much different than Negril. It is my gf's first time in Ja, so i thought I would give her a taste of both,and let her decide for future trips. Enjoy
