Rooms on the Beach includes breakfast & very nice rooms, price depends on room location or size & hotel is by all the beach bars but can still get some sleep.
Roots Bamboo is okay if you don't mind walking down property to bathrooms & showers since rooms are just bare boned cabins with narrow beds. Very basic accommodations & music will keep you up on their 1-2 night party time.
Fun Holiday is another I might suggest pricing, usually lots of Germans or Italians staying there & can be fun or close to fun bars.
Negril Tree House is farther down 7mile from bars but great place to stay for singles & includes delicious breakfast buffet with room price.
Coco La Palm I would not recommend for singles, its more family oriented.
Firefly is you don't mind nudity.
Across the road from beach are lots of cheap room options, depends on how basic a room you want or noise you are willing to put up with. I prefer to have quiet while I sleep & party elsewhere...
