At HNL:
I too got a good rate - $137 plus tax for a week - I think $169 or so total. But surprised to find out only I can drive the car; my husband can't also drive without another $12 a day......there went the savings. Okay, I'll do the driving, but we normally share it. I took this offer via the United Airline car rental promotion page, to get 1000 miles for booking there, so it had to stay in my name for me to get the miles.
I just never thought to check the fine print since at Budget, our regular company, not a problem for spouses to drive free.
The car has 35000 miles and the rubber lining where the trunk closes is falling off - otherwise okay. Lesson learned maybe, or, just get along for a week and read the T&C more closely in the future.
