You think it’s like anywhere else in the USA. Everyone speaks English. There are the same fast food restaurants, supermarket chains, Home Depot, etc.
You try to get from A to B and you get lost.
The street names are nothing like what they are in mainland USA. Sure, there’s a Main Street in Wailuku. But most street names are Hawaiian.
Ka‘ahumanu, Kanaloa, Pu‘unene, Waikea, Liholiho, Hina, Wahinepio …
The area names are equally fascinating: Kahului, Wailuku, Napili, Kanaapali, Lahaina, Kihei, Wailei, Makena, Kula, Makawao, Pukalani, Paia, Haiku, Huelo, Hana, Waikapu, Waiehu.
The Hawaiian language has fewer alphabet letters than the English language. It should be easier to remember — right? Wrong! You underestimate how difficult it is to remember something if you don’t know how to pronounce it.
