Two weeks really give you time to discover Oahu. After you check out the highlights mentioned in In One Week, visit historic Chinatown, take fabulous hikes, explore the waters surrounding the island, browse the art galleries and museums, go shopping, relax in spas, or take time to find unique experiences on the island.
Day 8: The Polynesian Cultural Center
You might want to sleep late today. Around or after noon, head for the Polynesian Cultural Center, in Laie. Allow at least 2 hours (if not the entire afternoon) to tour this mini-glimpse of the Pacific, where you'll walk through various "villages" filled with interactive activities, entertainment, and cultural events. Continue to dinner at Haleiwa Joes to avoid heavy traffic over the Pali back to Waikiki.
Day 8: Chinatown
See a different side of Hawaii by walking the streets of Honolulu's Chinatown. Plan to at least have lunch in this exotic part of Oahu. Then, spend the afternoon exploring the fabulous mansion (filled with Islamic Art) of heiress Doris Duke. You'll get the shuttle (pre-book a tour) from the Honolulu Museum of Art.
Day 10: Manoa & Diamond Head
Spend the day hiking, either into the rainforest or up to the top of an old volcano. Serious hikers might check out the Makiki-Manoa series of trails. Of course, after all that exercise, you might want to plan a massage in the afternoon at one of Hawaii's best spas. You'll deserve it.
Day 11: On the Water
See Hawaii from a different angle — get out on the water for a day. Even if you think you get seasick, take the lunch cruise on Navatek I. It's designed with stabilizers to guarantee that you won't get green around the gills. You can enjoy a great lunch and whale-watching in season as you cruise off Waikiki.
Day 12: Your Choice
Today's the day to circle back and do what you haven't before. It's possible that you didn't get to all of the sights in and around Pearl Harbor, so you may want to return for that. Or have a day at the beach: That's a big reason why you came to Hawaii in the first place, right?
Day 13: Art
Head to the galleries of Honolulu to get a feel for the contemporary art scene. We're particularly fond of the Gallery at Ward Center.
Day 14: A Sweet Ending
Finish your stay on the island with a fascinating, bean-to-bar chocolate tour. And then head back to your hotel to pack…and dream of your next visit.
