Hotel Features: Set on Waikiki's widest stretch of sand, Duke Kahanamoku Beach, the Hilton has five towers of rooms surrounded by a secluded five-acre lagoon, lush tropical gardens with exotic birds and a mammoth water complex with five pools. The 2,860 spacious rooms are hooked up with Wi-Fi (for a fee) and flat-panel TVs with premium cable. Some rooms have terrific ocean and Diamond Head views. The kids will love zipping down the waterslide (billed as Waikiki's longest) in the huge freshwater Paradise Pool or enjoying the fine children's program offerings. Maybe you'd fancy a surfing lesson, stand-up paddling, an Atlantis Submarine adventure or a catamaran sail. The pink flamingos, starlight luau (fee applies), and Friday music and dance extravaganza with fireworks are all big crowd-pleasers. This mega-resort village also has a Hawaiian art collection, a luxury spa, a wedding chapel, over 15 restaurants and bars and over 90 fine boutiques and shops. Parking is available for a fee. No
