There's a reason couples keep flocking here: It's incredible.
When to go: Anytime -- but October and November are especially exquisite.
Where to stay: First, hit Waikiki, where you'll luxuriate in freshwater pools at the newly face-lifted Royal Hawaiian, one of the original playgrounds for Hollywood royalty like Marilyn Monroe and Clark Gable. The resort is known as the Pink Palace of the Pacific, and for good reason. Next, for a different side of Hawaii, jet to unspoiled, locally beloved Princeville, Kauai, the site of Hawaii's first-ever St. Regis. There, 90 percent of the rooms overlook Hanalei Bay, which is widely considered to be one of the world's best beaches.
What not to miss: In Waikiki, book private beachfront cabanas with concierge service, and swim, paddleboard, or melt away post-wedding stress with a massage. Later, sip cocktails -- the Garden, Royal, or classic Scratch -- at the iconic Mai Tai Bar. Gobble fresh seafood (sourced at the local Pier 38 fish auction, the only one of its kind between Tokyo and Maine) at the new, innovative Azure restaurant, or on Monday nights, join the festive Aha Aina feasts (they're like luaus, but grander). In Princeville, hike to the Napali Coast, explore sea caves, wildlife refuges, and tropical gardens; consult private wellness experts to customize Halele'a Spa's Hawaiian healing rituals; and chow down at Kauai Grill, helmed by chef Jean-Georges Vongerichten (of New York City's Spice Market fame).
