The Ala Moana Bus will bring you to the Ala Moana Shopping Center. The center is the largest outdoor mall in the world. It is currently going through a 50% expansion. The Ala Moana Bus is air-conditioned and is more a shuttle than a bus. It runs every 15 minutes between the Ala Moana Shopping Center and eight convenient stops throughout Waikiki. The fare is $2.00 each way.
