I have been the main planner for our vacation to WDW 4/3 - 4/10 and I have 3 cars confirmed in my name with National. I need to know if it is possible to change 2 of the rentals to my sister and niece or do I just add them as additional drivers? If I just add them as drivers, can they pay for the rentals when we pick them up? 
Thanks.

Thanks.
