Closing Thoughts

Oahu is a beautiful island. Even today, too many visitors to Waikiki spend all of their time at their hotel or resort and never explore the beauty of the island, much of which is within minutes of the rooms. They return home and say that they have been to Hawaii when in reality they have missed what Hawaii is all about.
