My Aunt seems to like Negril almost as much as I do - she always seems to find a way to come along. I would suggest bringing what you need, if only so you don't have the hassle of sourcing new products to contend with. I will say that that in Negril, my Aunt seems to be pretty irie. On the island what is often a pretty miserable, crampy few days becomes a pretty mellow and almost painless non-event. I figure it is the combo of my extremely relaxed attitude and the warm Jamaican air.

Not to get really TMI, I do find my preference skews strongly towards tampons in the heat and humidity. I didn't bring the right ratio of product along the first time around.
