Falmouth Beach Excursion

[starvenger]

So we were looking at external excursions on a site I've used before as well as Viator, and saw one that looks good in Jamaica. Only thing is, it's a "Montego Bay" resort, which based on pictures I've determined is the Sunset Beach resort. Since transport is not included in this package, and the resort is about 40km (a full marathon) away from the cruise ship terminal, I'm wondering what the best method to get there would be? Not concerned about missing the boat as we're pretty paranoid and/or vigilant about getting back in time.
