I really can't say anything about the resorts in Negril per se, but I've been to Beaches in Turks & Caicos, which has the same parent company as Sandals, and the stay was amazing. Free SCUBA, meals were top notch, and they have a culinary concierge if anyone needs specialized meals due to allergies or medically necessary diets. You basically go see the concierge in the morning and order your lunch and dinner, advise them when you would like your reservation and they will have everything all set for you. Total professionals. Would highly recommend Sandals (no kids) or Beaches (with or without kids) if anyone in the group has dietary restrictions.
