My sister and I are taking our annual beach trip to St. Lucia this August. We are in our late 40s, married, and going without our spouses. We are looking for recommendations for hotels on the beach, quiet, no kids, but accessible. We are both active. We like good food, good alcohol, casinos, restaurants, outdoor activities. We are willing to rent a car, tho always love not having to. We typically split our time between outdoor activities and lounging on the beach. Budget is up to 500 a night, tho could go higher. Thanks!
