If you are from Wisconsin, would suggest you visit a local farmer's market. Some produce and the (tropical) flowers would be different from your area.

We vacationed and cycled for 3 wks. in Hawaii (in June) a few years ago. On islands of Big Hawaii and Kauai. And yes, the local market had CHEAP huge fresh papaya..and we gorged on that stuff.

The history of Hawaii is cool (to me) which is another reason I did want to visit Hawaii...because the history and cultural groups that make the islands....make it different from the rest of the U.S.

We visited a number of outdoor botanical gardens while biking. Got enough sun, that I had zero interest in lying out in the sun on the beach just to get a tan. I tan very fast even with sunblock.

WE stayed at bed n' breakfast places..which was better for us to get more island feel.

I was surprised by the number of wild hens and roosters running around. Never expected it, but it is an island ....and they have no other place to go, if they escape from a farm...

Make sure you taste and buy Kona coffee beans,...it's very difficult to buy in North American mainland. And try the macadamia nut products that are all over the place.
