If you want great golf, a nice beach, and a great pool you have to try the Marriott Beach Club at Lihue, Kauai. The Beach Club boasts one of the largest resort pools in the islands, has two golf courses up the hill (walking distance); one very challenging and the second for any level player. Additional golf at other island resorts, if you want more.
Great restaurants on island, though resort food is best at breakfast and lunch. Mai-Tai's are pretty good.
Plus, the weather is always 78 degrees, sunny and comfortable.
If you haven't been to the islands, Kauai is a great choice as it is out of the way and very quiet. You need to be ready for golf and relaxation, 'cause there isn't much night life.
