Renting a car from Alamo at LAX – do I need to buy extra insurance?

Hi all,

I’m planning to rent a car through Alamo at LAX for two days, but I’m a bit confused about the insurance side of things. I’m not from the US, so I’m not sure what I actually need to be covered.

Alamo is offering me the Collision Damage Waiver (CDW), but I don’t know if that’s enough or if I should be adding more coverage separately. I don’t want to be stuck with a huge bill if something happens, but I also don’t want to buy something unnecessary.

Anyone else rented from Alamo at LAX as a non-US resident? What did you do for insurance? Appreciate any advice :)
