Okay, so how far in advance before your return flight would you leave for the airport if you are taking the shuttle? 4 hours? Earlier?

We want to take the shuttle on the way there because my fiance has never been to Jamaica and wants to experience it. However, on the way home, I'd rather get a little extra time at Couples and fly back on Airlink. The only issue is that my flight is at 1:30 pm, so I would have to take the 10am Airlink flight (way earlier then the 2.25 hours prior to your flight that they recommend). So, if Airlink is leaving at 10am and we'd get on the shuttle at 9:30am, then it's not really saving us much time.
