Grand Wailea, A Waldorf Astoria Resort

While this luxurious resort, located on Maui's sunny southern shore, has much to offer, many feel that the sumptuous, 50,000-square-foot, aptly named Spa Grande rates as a destination in and of itself. Though this full-service facility has 40 treatment rooms, the spa prides itself on its very personal services. Its separate bathing areas for men and women, illuminated by natural light through windows of thick glass brick, are where one experiences the unusual range of healing water options that are a highlight of the huge spa services menu.
