I'm by no means an expert. But AIs in Negril do it a disservice .
Too many places to visit, bars, restaurants etc.
Walk the beach , venture up to the west end, more bars , restaurants and sights to see.
Venture during the day is no problem travelling solo. Nite more care is required. I was 26 once , trouble is easy to find if you look for it.
Just cab it. Many bars/restaurants offer shuttle one way.
Stay on the beach, white sands , charela , bar b barn many to choos from.
Get one with a breakfast plan to start your day.
Many like minded people on the beach to engage with or not if ou just want to chill.
Eating on the beach is a non issue ,the food will come to you if all you want to do is relax and be a lazy ass...
Many bars along beach will have entertainment and night life.
Again if near your hotel no problem . If further , at night ,cab it.
I'm sure many more will chime in.
2 weeks we'll be there, 9 days at Negril palms and 5 at samsara.
