Boy, not only is Las Vegas the favorite tourist spot for Hawaiian travelers, but the ubiquitous Hawaiian ABC Stores are also dotted around Vegas. The merchandise is slightly different than in Hawaii because on top of selling the Hawaiian stuff such as chocolates, coffee, souvenirs, they also sell Las Vegas stuff such as CSI: LV merchandise.
I guess you don't have to fly all the way to Hawaii to pick up some of your favorite island treasures anymore.
