NJRob,
Forget about renting a scooter or car in Jamaica and having a drink! Suicide!! Driving in JA demands total attention and absolutely no drinking or smoking for your safety as well as others. TB is a long ride over and back!! Do as others have suggested hire a driver and let him do the work. Sit back and enjoy the beautiful scenery, stop whenever wherever you want for a drink or a smoke. The roads in Westmoreland and St. Elizabeth are very challenging so leave it to those who know them and frequent them to carry you and your loved ones safely.
