We fly into Maui and spend 1 day driving to Hana and staying over night, then driving over to Kanaapali and staying at the Sheraton for 5 or 6 nights, and flying either Christmas day or the day after Christmas to Oahu and staying at the Hilton for 4 or 5 nights. I just can't decide if 4 nights and 4 days is not enough time at Oahu and 7 nights and 7 days is too much time at Maui. I've never been to either. We want to beach, snorkel, hike, go to Pearl Harbor, see the North Shore on Oahu, go to Diamond Back, see the sunrise at Haleakala, etc. I just wondered if anyone had an opinion for college aged kids. They are not much into shopping, maybe the daughter is, and they are will not be happy going to museums and gardens. Thanks. Lisa
