The staff saw that there were three of us and suggested upgrading to a Fullsize car. After using it, I felt that since I was only using the car for two days on Oahu, the upgrade wasn't necessary. The staff also recommended a service called Roadside Plus for $4.99/day, which provides emergency assistance if the keys are locked inside the car or in case of a flat tire. Later, I thought as long as I carefully manage the keys, the additional service wasn't necessary. Overall, I felt the company's staff were too eager to upsell extra services, which was not very good.
