It was convenient to be able to pick up and return the car right at the airport, and the car was clean and ran well. I would definitely rent a Nissan car again.
When making a reservation, I saw a phrase that said upgrade for rentals of 4 days or more, but the upgrade was refused on site because it was not included in the voucher. The car seemed to be new with 4,000 km on it, but the wheel caps were connected with cable ties, the interior was very poorly cleaned, and the window tinting was not at all like in Korean rental cars, making it very inconvenient to drive at night and during the day, you had to be exposed to direct sunlight (I heard that locals in Guam also tint their cars..). However, the fact that you can pick up and return the car right at the airport with your family is an advantage.
I've been to Guam over 15 times, and I always use Nissan Rent-a-Car at the airport. Previously, there was a promotion for free gas if you rented for three nights or more, but perhaps because of the rising cost of living, the free gas is gone, and the price has steadily increased, which is disappointing. However, since other places require driving into the city to rent a car, I plan to use Nissan Rent-a-Car if the price difference isn't too big.
This is my 5th time using Nissan Rent-a-Car... It wasn't difficult or anything. The only inconvenience is that the navigation system doesn't work most of the time, so I have to use my phone... I wish there was a phone stand. Haha. Thanks to you, I had a pleasant trip.
I've visited Guam three times and rented a Nissan car all three times. The car was brand new, with a rear-view camera, and it was incredibly comfortable. Parking was easy, and the grounds were spacious, making renting a car a must.
Overall, it was comfortable and pleasant. The staff was friendly. However, it seemed like they didn't consider optional vehicle upgrades unless specifically asked. It would be helpful to have a more thorough explanation of options and insurance.
I found it very convenient because the reservation site supports Korean and the local staff provides Korean guides. No need to worry about the language barrier!
