[[[ KEEP in mind, that i haven't been on-island in over 2-years ... so, my *feed-back* might-be TOTALLY wrong, but based on pass-trips/experiences ___ ____ ___ ]]]

'bout 11-pm
the BeachRoad (aka Norman Manley Boulevard, sometimes called Norman Washington Boulevard) WILL be jammed-packed with folks along the roadsides

lots pon beach-front too

traffic..??... --- in the past, as i recall, traffic was TERRIBLE..!..
:-(
getting around and/or out-of Negril was next-to impossible.

... whenever i go-over to Negril for NewYearsEve, i KNOW that-night, i ain't getting back to Lucea-country

over the years, the powers-that-be (e.g., Chamber of Commerce & police) instituted efforts to keep the traffic moving. Efforts primarily involved force-ing folks to park their cars on the roadside shoulder(s), and not sticking out into the road.

Some places have a little something-something on their properties. The bigger-FUN is roaming along the beach-front, hopping from place to place, & crowd to crowd. In fact, if you go to the back-of-the-house (aka The Beach Road), you're likely to stumble upon SEVERAL party-type gatherings. And of course, there're the properties on the euphemistically-called '..Garden Side..' ... i refer to it as the Swamp-Side.

Neverthless,

Dress..??... ----- lol lol lol lol lol lol ---- just don't be naked

Never-never forget::>> Negril touts itself as being:::> "..the Capital of Casual.."

so,
don't worry your-self about dressing-up, etc, unless you feel like it ---- no biggie ... NOT a concern. EXCEPT *maybe* at one of those hoity-toity all-inclusives, with the jacket-only dinner rules.

the odds are pretty-good that there'll be some-somebodies doing a private-dress-up dress-to-impress get-together. BUT as with most-things Negril-lian, cash rules..!!!... You got the cash (e.g., for cover-charge), you get-IN [[ period ]]
