I haven't actually done the pub crawl myself, but from what I understand it is on Wednesdays and the bus picks you up at your hotel about 2:00 and takes you to a few different bars along the cliffs and it ends at about sunset.
I've read about others experiences and it sounds like a great time!
I'm really hoping to fit it in this trip, but we'll have to see how the day turns out. You will find in Negril that plans don't always turn out as expected
