Where to rent a car in Honolulu and what the major companies charge

The largest rental companies in Honolulu operate from Daniel K. Inouye International Airport (HNL) and from locations in Waikiki and downtown. Enterprise, Hertz, Budget, Avis, and National all have airport counters, which is where most visitors pick up. Airport rentals typically cost 10 to 15 percent more than off-airport locations because of facility fees the airport charges the rental company — those fees get passed to you.

Daily rates vary by season and car type. A compact car in low season (September through November) might run $35 to $50 per day at an off-airport location, while the same car in peak season (December through March) can jump to $70 to $120 per day. SUVs and larger vehicles cost roughly 50 percent more. These are base rates before taxes, which in Honolulu add roughly 11 percent to your total, plus a vehicle rental tax of 1.25 percent on top of that.

Smaller local companies like Thrifty, Fox Rent A Car, and Alamo sometimes undercut the major chains by $5 to $15 per day, but they have fewer locations and longer wait times at pickup. If you are renting for a week or longer, ask about weekly rates — most companies drop the daily rate by 15 to 25 percent when you commit to seven days.

Key Takeaways

  • Airport rentals cost more than off-airport pickups because of facility fees, so booking from a Waikiki location saves 10 to 15 percent on the base rate.
  • You will need a valid driver's license from your home country or state, a credit card in your name, and proof of insurance before you can rent.
  • Decline the rental company's damage waiver if your personal auto insurance or credit card covers rental cars, because the waiver often costs $15 to $30 per day and duplicates coverage you already have.
  • Book directly with the company's website rather than through third-party sites, because the rental company controls what insurance options are available at pickup.
  • Parking in Waikiki costs $5 to $15 per day at public lots, and many hotels charge $15 to $25 per day if you park on their property.

What documents and insurance you need before pickup

You must bring a valid driver's license — a U.S. state license, an international driving permit, or a license from your home country. The license must be current (not expired) and in Roman characters if it is from a non-English-speaking country. You will also need a credit card in your own name; rental companies will not accept debit cards or cards in someone else's name, even if that person is traveling with you.

Insurance is the biggest variable. If you already carry auto insurance in your home state or country, check your policy documents or call your insurer to confirm whether it covers rental cars in Hawaii. Many U.S. policies do, but some exclude rentals. If your policy covers rentals, bring proof — usually a copy of your declarations page or a letter from your insurer. Credit card companies like American Express, Visa, and Mastercard often include rental car coverage if you charge the full rental to that card, but the coverage is secondary (it pays only after your personal insurance is exhausted) and usually excludes SUVs and luxury vehicles.

If you have no coverage, the rental company will offer a damage waiver (sometimes called Loss Damage Waiver or LDW) for $15 to $30 per day. This waiver protects you if the car is damaged or stolen, but it does not cover traffic violations, towing, or fuel. Read the terms carefully — some waivers exclude damage from off-road driving or driving on unpaved roads, which matters in Hawaii because some scenic drives use rough terrain.

How to book and what to expect at the counter

Book directly through the rental company's website rather than through Kayak, Expedia, or other third-party booking sites. Third-party sites often show a lower advertised rate, but they do not control what insurance options are available when you arrive at the counter, and you may not be able to decline coverage you do not want. Booking directly gives you the most control over your final bill.

When you book, you will see the base rate, taxes, and sometimes a vehicle rental tax listed separately. Some sites show the total upfront; others add fees at the end. Read the fine print to see whether the quoted rate includes unlimited mileage. In Hawaii, most rentals do include unlimited mileage, but some budget companies cap mileage at 100 to 150 miles per day and charge $0.25 to $0.50 per mile over that limit. For a week-long trip, this can add $50 to $150 to your bill.

At the counter, the agent will ask whether you want to add the damage waiver, a fuel option, and GPS or phone mount rental. Decline the damage waiver if you have coverage. For fuel, you have two choices: prepay for a full tank (usually $50 to $70) and return it empty, or return it at the same level you picked it up. Prepay is cheaper if you will use most of the tank; otherwise, return it full yourself at a gas station near the airport or your hotel. Do not rent GPS from the company — use your phone's maps app instead, which is free and works offline if you read the map beforehand.

Driving in Honolulu: roads, parking, and what to watch for

Honolulu traffic is heaviest on H-1 (the main freeway) during rush hours (7 to 9 a.m. and 4 to 6 p.m. weekdays). If you are arriving at the airport during these times, expect slow movement from HNL to Waikiki or downtown. The H-1 is straightforward, but merging is tight and drivers move fast once traffic clears. Speed limits are 55 mph on the freeway and 25 to 35 mph on city streets.

Parking in Waikiki is tight and expensive. Public lots near the beach charge $5 to $15 per day depending on location and time of day. Many hotels charge $15 to $25 per day for guest parking, and some charge more. Street parking is free in some neighborhoods but limited to two hours, and parking enforcement is active. If you are staying in Waikiki, ask your hotel whether parking is included before you book the rental — if it is, you may not need a car at all, since Waikiki is walkable and has good bus service.

One-way rentals (picking up at the airport and dropping off in a different city) are not practical in Honolulu because the island is small and there is only one major airport. Dropping off at a different location on Oahu (like downtown Honolulu or the North Shore) may incur a $25 to $50 drop-off fee, so confirm this before you book.

Fuel, tolls, and hidden costs to budget for

Gas prices in Hawaii are typically 30 to 50 cents per gallon higher than on the mainland because fuel must be shipped. As of early 2024, regular unleaded costs roughly $3.50 to $4.00 per gallon in Honolulu, though this varies. Fill up before you return the car — rental companies charge $5 to $8 per gallon if they refuel it for you, which is roughly double the pump price.

Honolulu has no toll roads, so you will not encounter toll charges. However, if you drive to the North Shore or windward side, some scenic drives use private roads that charge a small fee ($2 to $5) to access them. These are rare and clearly marked.

Traffic violations are expensive. A speeding ticket costs $100 to $300 depending on how far over the limit you were. Parking violations cost $50 to $100. If you receive a citation, the rental company will charge you an additional $15 to $25 processing fee and may report it to your credit card company if you do not pay it before you leave the state.

When to rent a car in Honolulu and when to skip it

Rent a car if you plan to explore the North Shore, the windward coast, or Diamond Head, or if you are staying outside Waikiki where bus service is limited. A car gives you flexibility to drive at your own pace and visit smaller beaches and hiking trailheads that are not on the tourist circuit.

Skip the rental if you are staying in Waikiki for three days or fewer. Waikiki is walkable, the bus system (TheBus) is cheap ($2.75 per ride, $5.50 for a day pass), and parking will cost more than the bus. Uber and Lyft are available throughout Honolulu and cost $10 to $20 for most trips within the city, which is often cheaper than parking alone.

If you do rent, book at least a week in advance during peak season (December through March). Rates are lower when you book early, and you have a better chance of getting the car type you want. Last-minute bookings in peak season often result in an upgrade to a larger, more expensive vehicle because the company has run out of compact cars.

Frequently Asked Questions

Do I need an international driving permit if I have a valid license from my home country?

No, but an international driving permit is helpful if your home license is not in English or Roman characters. Most rental companies will rent to you with just your home country license, but police may ask for an international permit during a traffic stop. You can get one from your home country's automobile association before you travel.

What happens if I damage the car and I declined the damage waiver?

Your personal auto insurance or credit card coverage will pay for repairs, up to your policy limits. You will be responsible for the deductible (usually $500 to $1,000). If you have no coverage and no waiver, you will owe the full repair cost, which can be $2,000 to $10,000 for major damage. This is why confirming your coverage before you decline the waiver is critical.

Can I rent a car if I am under 25?

Yes, but most companies charge an underage driver fee of $15 to $30 per day for drivers under 25. Some companies have a minimum age of 21; others require you to be 25 with no fee. Check the rental company's policy when you book, because the fee is not always shown in the initial quote.

What if I need to extend my rental after I pick up the car?

Call the rental company as soon as you know you need extra days. Extending at the counter or over the phone usually costs more than booking the full period upfront, but it is cheaper than returning the car and renting a second one. Rates may also be higher if the company has fewer cars available on the extension dates.

Is it cheaper to rent from the airport or from Waikiki?

Off-airport rentals in Waikiki are typically 10 to 15 percent cheaper because they do not include airport facility fees. However, you will need to get to the rental location from the airport, which costs $15 to $30 by taxi or rideshare. If the savings on the rental are less than your transportation cost, book at the airport instead.
