I have been to Oahu, Maui and the Big Island. In Wailea, we love the Four Seasons, which is right next to the Grand Wailea. We have also stayed at the Kilauea Lodge on the Big Island as well as the Four Seasons on the BI. If you want more of an adventurous honeymoon, I would go to the Big Island. When we were there two years ago, I was very disappointed because the lava was not flowing where you could see it. I understand this was not the norm. But the Four Seasons on the BI is one of the nicest hotels in the world. We are going back to Hawaii in January and we are staying 10 days on Maui at the Four Seasons. There is alot to do on Maui, if you want, or you can be lazy and spend the day on the beach watching the whales. We have also been to Oahu twice and I would recommend a stop there as well. Pearl Harbor is just such an amazing part of our history and so very moving. We also climbed Diamond Head, went to the North Shore, Poly lookout and there is a bay which is a crater that is great for snorkeling. The fares to island hop, if you have the time, are not too expensive. I just love Hawaii!
