I was in Negril a couple years ago, you're gonna love it. And to your point, yep, I'd just bring your own. There are a couple places to get cigars but I would say the legitimacy is questionable at best. There is the duty free at the airport in Montego Bay, but I don't know that you can get to the shops as you exit the airport. Was kinda strange to me.
Anyway, bring your own, congrats on your marriage, and enjoy the hell out of Negril.
