Budget Guam Car Rental Tips for Students and Groups | e-Rent-A-Car

(Updated )

For students and groups, sharing one rental car can reduce the cost per traveler. The daily vehicle rate is only one part of the budget, however. Additional drivers, optional protection, fuel, parking, and the taxi from the airport all matter. The reliable way to save is to compare the total transportation cost for the entire trip.

Key points
  • Budget by the total trip cost, not the daily rate: add protection, additional drivers, child restraints, fuel, parking, and the airport taxi fare and tip.
  • Additional drivers cost $5 per person per day, and accidents or damage involving an unregistered driver are excluded from coverage, so register everyone who may drive.
  • Early returns are not refunded on a prorated basis, so set your driving days before booking. Cancellation has no fee, but a change means canceling and booking again.
  • The airport taxi to the Tumon office runs about $20 plus a 10–15% tip, and the receipt earns $15 off the rental charge under the current promotion.
  • Declining protection lowers the amount paid at booking but can leave you paying much more after an accident, so e-Rent-A-Car recommends adding CDW, ZDW, and NOC for peace of mind.

Calculate the total rental cost first

Add up the following for the same dates and conditions:

  • Vehicle charge for the required rental days
  • Selected protection such as CDW, ZDW, and NOC
  • Additional drivers and child restraints
  • Fuel and parking
  • Taxi fare and tip from the airport to the office

The $100 amount placed on the card at pickup is a temporary preauthorization under the current terms. It is not a normal rental payment transferred to the company, but it temporarily reduces the credit available on the card.

Share common costs, but register every driver

The group can divide common expenses such as the vehicle and fuel. But don’t skip driver registration. The current terms list an additional-driver fee of $5 per person per day, and accidents or damage involving an unregistered driver are excluded from coverage. Register everyone who may drive when signing the agreement.

The smallest class is not automatically the best value. If luggage does not fit and the group needs two cars, or if a fully occupied car is uncomfortable for longer drives, the apparent saving disappears. Check passenger and luggage capacity before booking.

Rent only on driving days—but finalize the itinerary first

One option is to separate days spent around Tumon from days planned for northern or southern Guam, then rent only when a car is useful. The current terms do not provide prorated refunds for an early return, so define those driving days before making the reservation.

The official guide says reservation cancellation has no handling fee, but a change requires canceling and booking again. Your preferred class may no longer be available when you rebook, so do not build the budget around repeated changes.

Use the hotel shuttle and airport taxi promotion correctly

Complimentary round-trip transportation is offered between the office and Tumon hotels. Leopalace Resort guests connect at Guam Plaza Resort & Spa, while Starts Guam Resort guests connect at Reef Hotel. Confirm the time and meeting point in advance.

There is no pickup from the airport. The company currently estimates the taxi fare to its Tumon office at about $20, plus a suggested tip of about 10–15%. Present the airport taxi receipt at check-in and the current promotion discounts $15 from the rental charge. No receipt means no discount, and it cannot be combined with another discount. After you return the car, a free shared shuttle can take you to the airport or your hotel.

Choose protection by risk, not price alone

The base rate includes liability protection for injury or damage to the other party, but it does not broadly protect the rental vehicle itself. Under the current terms, optional CDW limits what you pay for repairs to the rental car (up to $50,000) to a $1,000 deductible, and applies to car-to-car collisions with both drivers present. Without CDW, you pay the full repair cost. ZDW can be added only with CDW and waives that deductible. NOC protection addresses the loss-of-use charge while the vehicle is being repaired.

Exclusions still apply even with every option, but we strongly recommend adding coverage for peace of mind. Compare what each option covers and what your group would have to pay after an accident before deciding.

Prevent avoidable charges for fuel, condition, and keys

  • Fuel: Most vehicles take regular unleaded (Shell FuelSave at Shell stations). Fill the tank on the return date and show the receipt when you return the car.
  • Interior: Wet seats, sunscreen stains, sand, and mud may lead to cleaning charges depending on condition.
  • Keys: Protect the key from loss and water, especially at beaches and pools.
  • Return time: Contact the office in advance if the group may miss the contracted return time.

Budget checklist

  • Calculate vehicle, protection, options, fuel, parking, and airport transfer
  • Select a class that fits passengers and luggage
  • Register everyone who may drive
  • Separate driving days from non-driving days
  • Confirm hotel-shuttle eligibility and meeting point
  • Keep the airport taxi receipt
  • Read coverage and exclusions before signing
  • Manage fuel type, return time, interior condition, and keys

Frequently asked questions

Is there a student discount?

As of September 13, 2026, the official site does not publish a student-specific discount. Sharing common costs, renting only on planned driving days, and using eligible transportation offers are more dependable ways to reduce the total.

Does a larger group always pay less per person?

Only when everyone and the luggage fit safely in one suitable vehicle. A larger class, extra drivers, or child restraints can change the total, so compare complete quotes.

Is declining all optional protection the cheapest choice?

It lowers the amount paid at booking, but you could end up paying much more out of pocket after an accident or damage. Liability protection, CDW, ZDW, and NOC each cover different risks, so we recommend adding them for peace of mind.

Summary

A budget Guam rental is about the full trip cost, not just the lowest daily rate. Pick one appropriately sized vehicle, define the days it is needed, register every driver, use eligible transportation, and include protection and return conditions in the calculation. That approach reduces surprises without cutting essential safeguards.
