Oahu has reached a saturation point. So has Maui. Look at Kailua, and tr;y parking in Lanikai on 3 da;y weekends. Check Waimanalo beach out and Hanauma Bay. Waikiki is almost to the point of too many people on the sidewalks along with the 2 wheeled electric vehicles. Try enjoying the sunrise at Haleakala or walking around in Lahaina. Those days are gone for the locals.
