Falmouth was fun enough for shopping but wasn't authentic Jamaica. If you leave the gates without an excursion watch yourself. Be prepared to be hassled until you return. While I enjoyed the shopping I felt a bit taken advantage of by the cruise line since this wasn't a TRUE port but more of a creation by them to make money. A power plant is in the backdrop but the little town is cute enough. Would prefer Ochos Rios or Montego Bay honestly.
The beaches at adrenaline beach are great to lay out in but be prepared for rocks EVERYWHERE in the water! Watch your feet and don't cut them. Look for the light colored water, this is clear sand areas out deep. The activities on the island are abundant but will cost you. Get a drink package, you can use it on the island! The zip line looked like fun but wasn't about to pay 98 pp for a 90 second trip down a mountain. The coaster was a lot of fun but still a bit pricy. Beautiful cliffs and surroundings though and all facilities are well taken care of and manicured.
