What to expect: The Grand Hyatt Kauai is a self-contained resort arrayed on 50 naturally contoured, lavishly landscaped acres overlooking the blue Pacific. Located at an isolated end of South Kauai, the hotel is popular with celebrating couples and families.

Amenity highlights: Spiritual and physical rejuvenation can be found at the renowned ANARA Spa, with lava-rock showers; thatched-roof treatment huts; and yoga, meditation, and other classes. The resort's expansive water park includes a 1.5-acre saltwater lagoon with beach, a 150-foot water slide, and an artificial river meandering from the hotel through lush gardens and hidden grottos and under waterfalls to a freshwater lagoon pool.

Insider tip: The "Share the Stars" dining option allows guests to enjoy a secluded dinner with a private server at a linen-draped table near the beach.

What to expect: Spread over 20 acres of oceanfront, the 394-room Sheraton Kauai appeals to families and romance-seeking couples. The soothing sound of surf rolling across the lava-rock point in the resort's center contributes to the relaxing ambience. No building rises higher than a mature coconut tree, ensuring that the resort fits into its splendid setting.

Amenity highlights: The crescent of pale, powdery sand extending a quarter-mile from the Sheraton's center is irresistible, and excellent snorkeling waters border the resort's lava-rock point. There are two pools: one, with a slide and an adjacent spa tub, is near the beach; the other is across the street in the resort's northern section. An oceanside lawn provides a popular sunning spot.
