I have traveled to Oahu 3 times and I will go back, BUT outside of Waikiki the public restrooms at the beaches are the most discusting I have ever seen , my wife refused to use them ,there were razor blades and other not so nice thngs laying all over the places,and at Sharks cove there was human fecus all over the walls and it was still there after our 2 week holiday was over, just pure ugly side of a beautiful Island, plus i must admit the locals can be rude
