Yup. Similar experience when we stayed there, maybe a year and a half ago. Only 2 other rooms occupied on the large property - one of them by a women who rented a studio room for an extended stay. They would cut the power to the A/Cs during their karaoke night, so that they can run the sound system. (This frustrated my wife because karaoke night was the night we arrived and she just wanted to go to our room and crash for while). That said, karaoke night was pretty fun with a good mix of locals and tourists, the bar was hopping and they had decent jerk barrel on site. NE is, in fact, owned by the family that owns the Jungle. They also own Boardwalk Village and provide free shuttle service to both venues.
Negril Escape seems to be pretty active on Facebook, as of late. I hope this means that there is new management and a renewed interest in the property. In the recent past, it seemed the owners concentrated their efforts on Boardwalk Village and The Jungle.
