Built by a Japanese multimillionaire at the pinnacle of Hawaii’s fling with fantasy megaresorts, the Grand Wailea is the grand prize in Hawaii vacation contests and the dream of many honeymooners—but it’s better suited to families and couples who like some hustle and bustle. No expense was spared during construction: Some $30 million worth of original artwork decorates the grounds, much of it created expressly for the hotel by Hawaii artists and sculptors. More than 10,000 tropical plants beautify the lobby alone, and rocks hewn from the base of Mount Fuji adorn the Japanese garden. Humuhumunukunukuapuaa, the excellent, Hawaiian-themed restaurant (named for the state fish, and nicknamed Humu), floats atop an artificial lagoon, and light filters majestically through the stained-glass walls of the wedding chapel. Guest rooms come with lavish, oversize bathrooms and plush bedding. But for kids, all that matters is the resort’s unrivaled pool: an aquatic playground with nine separate swimming pools connected by slides, waterfalls, caves, rapids, a Tarzan swing, a swim-up bar, a baby beach, a lazy river, and a water elevator that shuttles swimmers back to the top. If this doesn’t sate them, an actual beach made of real golden sand awaits just past the resort hammocks. The Grand is also home to Hawaii’s largest and most resplendent spa: a 50,000-square-foot marble paradise with mineral soaking tubs, thundering waterfall showers, Japanese furo baths, Swiss jet showers, and many other luxe features, but large and lively groups can make it less tranquil than other spas. Those looking for more room and a bit more privacy should try the Villas at Hoolei, adjoining the Grand Wailea Resort, with shuttle service between the two. The 3,200- to 4,000-squarefoot, three-bedroom, three-and-a-half-bath, two-story villas have it all: elevators, gourmet kitchens, two-level covered lanai with gas grill and refrigerator, and access to all resort services and amenities
