3 nights in Negril? I'd do the pub crawl one night (as you are doing). During the day, I'd switch between sitting in a lounge chair and walking up and down the beach to check out the different bars. I'd feast on patties, jerk pork & chicken and fresh fruit - washing it all down with cold Red Stripes or Rum & Tings! After the sun sets, I'd play it by ear based on my mood. You'll meet plenty of people at White Sands to hang out with if you want! Definitely stop by Sunnyside for some beverages!
