Tax assumption
Default planning estimate for Oʻahu in 2026: 11% Hawaiʻi TAT + 3% Oʻahu TAT + up to 4.712% passed-through GET. A hotel’s actual invoice structure can differ, so edit this if your quote shows another rate.
Prefilled prices are hypothetical examples, not live quotes. Enter the parking nights separately: a same-day rental may need no overnight parking. Use the fees shown by your hotel or booking provider. Check whether parking taxes or extra charges apply to your quote.

WAIKIKI HOTEL COST GUIDE
Why the cheapest Waikiki room rate may not be the cheapest stay
Compare the all-in total. Resort fees, Oʻahu accommodation taxes and hotel parking can materially change the cost of a Waikiki stay.
Two hotels with similar nightly rates can end up hundreds of dollars apart over a week once mandatory fees and parking are included. Use the calculator above with the fee information shown on the hotel or booking page, then compare the final stay cost rather than the advertised room rate alone.
What to include when comparing Waikiki hotels
- nightly room rate for the same dates and room type;
- mandatory resort or destination fees;
- estimated lodging taxes;
- parking only for days you will actually have a car.
A hotel that costs slightly more per night can still be cheaper overall if it reduces parking, transport or other trip costs.
