Aloha. Arriving on Oahu on a Sunday vrey early afternoon. Leaving for Maui on a 1pm flight on Tuesday. We have been to Oahu, but it was nearly 20 years ago. Husband would like to see the Arizona again. While he does that, I might explore gardens, walk the beach, shop, find a yoga class. We would like to hike Diamond Head, and I think a drive along the North Shore is in order. That all said, am I missing something spectacular, and in what order and time frame should I do this? Thanks to all!
