It would be easier to respond if you provide some more info. Such as:

What are your required amenities – air conditioning or will just fans be okay (rates are much cheaper if no a/c); do you need a full kitchen or can you make do with just a small frig and a coffee maker; does it have to be one unit large enough for 2 couples/4 people, or would adjoining rooms with a shared kitchen work or would 2 rooms in the same property suffice.

And as Bnewb noted … what is your price range, ie under $100/night plus taxes, under $200/night, under $300/night, etc specifying if the range is for 2 persons or 4 persons There is accommodation in Negril for every price range!

You are wise to start your research early – February is the busiest month in Negril and many of the repeat travelers book their accommodation months in advance to get their favorite rooms.
