There is a post on the Facebook page On the Road to Negril.

The post is from Erin who is currently in Negril.

In her post she mentions there is NO POWER in Negril, unless a hotel has a generator and fuel.

NO POWER means no ATM/ABMs or credit card usage!!!

CASH ONLY!

So unless you are willing to pay with CASH for everything, I suggest you don't go.
