When you do "pay now" with Hertz, when you show up do they authorize the full rental + deposit (assuming not using VISA), or since you already paid the rental fee, just the $200 additional authorization?

I'm going to be booking a two week reservation and if they're going to charge the full rental amount + deposit even if I do pay now, I may just pay the extra $75 so I don't have that additional hold on the card even after I've paid the rental.
