Ah yeah, I thought about that as soon as I submitted that you were probably staying on the beach.
Then yes, try one cliffs and one beach, so 3 dives and Kuyaba
However, I recommend you at least see Catcha Falling Star....you could stop by for a drink at Ivans bar, or maybe even lunch, but its definitely worth seeing the property! Or maybe even go for a drink before you head to 3 dives for dinner/sunset....during the time you are going it is usually slow so the staff at Catcha would gladly allow you in for a drink or even just a tour around the property!
You are going to love Negril.....I can't wait to hear your trip report....it is so fun reliving that "First time experience" whenever a newbie goes
Have a blast....I'm right behind you
