Are there any companies that don't add a daily fee for not being the age of 25?

That's pretty much a normal thing for all rental car companies. For under 25 they require the extra insurance.

All car rentals added for insurance purposes.

Call and ask for a solid answer.

Unsure

I think every company does that as extra insurance.

That is pretty much the norm. Has been for a long, long time.

Not that I know of.
