If you go to the office of nature for lobster ask to see them first or they may try to slip you some smaller sized lobsters. They are excellent though. If you go off the property try not to let the locals know you are staying at the RIU. You will become an instant target for the higglers. Last time I stayed at an AI we had to wear the bracelet things and they pick up on that right away. You will love Negril have a great trip. Cosmos is not to far from there either for some good food and local atmosphere.
