I finally made it back to Hawaii to finish the collecting I started 6 years ago. This time I made the rounds on Oahu. The machines in Waikiki were fairly easy as our hotel was mostly within walking distance. A couple of the presses were gone due to construction and one was missing completely.
Among the highlights of the trip were Pearl Harbor, air museum, the Dole plantation, and the Polynesian cultural center (which also had a broken machine). I also searched the inside of the new Disney resort but found no machines much to my surprise. I managed to bag a mere 70 pennies in total, falling short of my expectations, but leaving just enough to warrant another trip back.
