Larry owns most of the island, and there are only a few locals, most working for him. There is minimal visitor support, such as hotels, restaurants, car rentals and touristy sites. Larry owns all the hotels for example. It wouldn't surprise me if all car rentals (besides 4x4 Jeeps etc.) are EVs real soon.
Lanai might be the first "almost" all-EV location in the world. Lots of chargers and charging locations will be part of that.
