Need some resort recommendations

Hi, my friends and I are planning a relaxed stay at a local resort for a few days. Our group consists of 5 guys and 3 girls, all over 23 years old. We are looking for a place where we can drink privately, preferably with beachside access. Additionally, if there are provisions for barbecuing, that would be great. To be clear, alcohol consumption will be strictly within private units, with no public drinking. Are there any such group-friendly resorts in Chennai that meet these requirements?
