We stayed here two years ago, in an Oceanview Room in the Rainbow Tower, and now we're back and staying in an Oceanfront Room in the Ali'i tower. This is a great place, walk out of the hotel lobby and onto the sands of Waikiki Beach. The resort covers several acres, packed full of shops, restaurants, bars, everything - and then a simple stroll down the beach and you're in the main shopping area of Honolulu. The Ali'i Tower and the Rainbow Tower are similar in price, the difference though in the Ali'i Tower is that it's like a special club within the larger resort. There's a dedicated Concierge, many perks such as free water etc, a dedicated level 2 area that contains a gym, a swimming pool with deck chairs, and a bar with tables and chairs. You also get a leather wristband that they suggest you wear on the premises, and that gets you front of line access to all the Hilton owned restaurants on the property, and that's proved to be very handy. Highly recommended, and we wouldn't stay anywhere else in Honolulu.
