Ditto this. Especially the comparison to the Jersey Shore. The wife and I are looking into a long weekend at Cape May for Valentines Day. Hotel prices are easily $200+/night - in the wintertime, when you can't even enjoy the beach! (That's another thing - in Jersey the ocean is really only warm enough to swim in 2-3 months out of the year. Jamaica enjoys a warm current all year round.) I could get a pretty sweet room in Negril for that price, even during high season. In fact, I have never paid that much for a room in Negril.
Basically, it's hard to justify paying more for a destination when you know you will enjoy Negril more. The food, the music, the people, the activities, the vibe, the culture.
