I placed an order in March and arrived at Maui on 9/28. Upon entering Dollar and submitting the order, they started adding mandatory insurance. I already mentioned that I would pay according to the order, but they said the insurance in the order only covered a part. Finally, I asked if I couldn't rent the car if I didn't buy the additional insurance, and she said yes. At that moment, I didn't have time to contact the car rental website due to long flights and anxious family members. So, I had to buy whatever insurance they told me to. The return process was relatively smooth. I pre-paid for a full tank of gas, so I could return the car with any level of fuel.
