Hi all, for some background, I am 22 and Avis Preferred Plus. I have a few questions about when you need to go to the desk vs when you can just take a car and leave.

1. Is it correct that in general, the prices for people younger than 25 are far more expensive?
2. When I am logged in to my Avis account, I can't change my age (it's grayed out and locked). What prevents me from just making a booking while logged out and designating my age as 25?
3. Can you only do car pickup without going to the desk if you are Preferred Plus?
4. I found a booking where the corporate code I usually use is actually more expensive than the base rate. The scenario is as follows. If I am logged out and put my age as 25 without my code, it is actually cheaper than being logged in (and therefore age set to 22) with my code. What is the right thing to do here?
