mi been der for the last three and will be der again this Summer....since mi always der in Summer
you will never see more people in Negril than during Dream Weekend which is actually a week long thingy......
on the Cliffs you can see the up tick in people......but on da beach is where you see a ton of people.....
people save up for this Dream Weekend and yes it is an older adult Spring Break.....
unfortunately the beach road can get like a parking lot.....especially near the events/parties when dem going on
personally mi like it as it great for people watching....to mi it doesn't last very long and there are no big intrusions.....
just make sure if you der then....stock up on items you need.....as many stores run out of stuff......

Cool Runnings, Marko
