There are many cool things to do at the Dole plantation. That's Dole, as in Dole pineapples. It's kind of a giant tourist trap. The only activity we paid for was the maze - you have to go around and find these little stencils and color on your little card.
The Lonely Planet says it takes most people 15-30 minutes. It took us 33. The record time is five minutes. I think you'd have to do it an awful lot to get down to five minutes.
Also, you can have your picture taken in a pineapple cut-out. I had mine taken as the pineapple doing the hula, of course.
HOW CUTE is this baby pineapple?
