Oahu No Ka Oi

Oahu is the cheapest, hands down (Merc)

The answer has long been obvious, even if the visitor doesn't have a free "hotel" and car like your humble blogger:

What’s the cheapest Hawaiian island to visit? [bold added]

Of the four main Hawaiian islands for tourism — Oahu, Maui, Kauai and the Big Island — Oahu is the cheapest Hawaiian island to visit by multiple metrics. Oahu has the lowest daily average hotel room rate of the islands and the lowest average daily spending per tourist, according to May 2024 data from the Hawai‘i Tourism Authority.

Though the average room rate in May 2024 across all of Hawaii was $342, Oahu hotel rooms average about 21% less, coming in at $272. That translates to about $70 per night less than the average...

One reason for Oahu’s lowest average room rate? The island also has the biggest supply. In fact, Oahu had more than double the number of hotel room nights than Maui, the next closest contender...

So why is spending on Oahu lower than on other islands? Not only are there more hotels, but also more restaurants and other types of businesses. According to the latest U.S. Census Bureau data, Honolulu County in Oahu had more than 21,000 businesses in 2020, while Maui County in Maui had fewer than 5,000. The increased competition lowers prices for consumers.

There’s also just a lot of free and cheap stuff to do on Oahu. Many of the top activities — including visiting the Pearl Harbor National Memorial, lounging on Waikiki Beach and hiking the Makapuʻu Point Lighthouse Trail — are free. It costs just $5 per person to enter Diamond Head State Monument (though it’s an additional $10 for parking).

And because of Honolulu’s robust bus network and walkability, it’s easy to get around Honolulu without a rental car. For places more difficult to get to, it’s possible to rent a car for just a day or rely on rideshare services like Uber or Lyft.

I use my parents' house and Nissan Altima when I go to Oahu, so I'm able to keep the trip cost to under $1,000 including plane fare. Even so, I typically only use the car to visit Mom in assisted living and like to spend my free time hoofing it around Waikiki and Ala Moana, where there are many quality, inexpensive restaurants.

Some of my friends, whom I like despite their snootiness, only go to the Neighbor Islands. I'm not ashamed to say that this middle-class kid prefers Oahu.
