Friends got to HNL yesterday and are very angry and upset with customer service for Dollar. The rep refused to add additional drivers - wanted $12/person per day, didn't want to upgrade either. They paid for 2 door Wrangler, but asked for 4 door. Ended up paying over $400 for the 2 door Wrangler for 9 days with insurance.
I suggested to cancel their Dollar reservation at OGG based on HNL experience.
This is contrary to experience with National at LAX, which was excellent. Ended up with mini van for $206 for 5 days. There was a huge number of small SUV's for 4 people, but we needed a larger car.
