We will be reserving an Alamo rental car via Costco. My understanding is that:
1) We get a free additional driver thanks to the Costco factor
2) Alamo allows the 'renter's' spouse to drive at no additional charge as long as they meet the requirements

My question: Does Alamo allow *both* official drivers' spouses to drive?

Our son will be the one renting through his Costco account, and he will include my husband as his additional driver. Alamo should also allow son's wife / our DIL to drive. What I'm trying to figure out is if, as my husband's spouse, I can also drive per Alamo's rules.

TIA!
