A great alternative would be Charela Inn - great location on beach, good sized pool, some of the best food in Negril at their restaurant (specializing in both Jamaican and French cuisine), Jamaican owned and operated (Daniel Grizzle is Jamaican, and his wife Sylvie is originally from France ... both are long time members and Directors of the Negril Chamber of Commence). Would also be less expensive than Couples.
