Yes, it is true there is no electric in Negril. The hotels that are open are running on generators. I can't be 100% positive, but it seems that the beach road has water, even some of the small restaurants. You are correct, contact your hotel to see if and when they will open. We had been scheduled for Home Sweet Home but when we walked there yesterday we knew they wouldn't be ready until after we left Jamaica. So we extended our stay at Coco la Palm.
