If you do end up picking up your friend, have her check over her resort folio/bill very closely on check-out for erroneous parking charges.
There is a discussion thread elsewhere on Disboards regarding guests being charged for parking when they had no vehicle parked. (My spouse and I were among the "victims.") A common thread among several having reported being wrongly charged was having had someone visit them or having something delivered to them. (We had a pharmacy order delivered.)
Speculation was that in the process of verifying the guest for whom a delivery/visit is being made, security CMs at the gate may, due to a system glitch, be inadvertently triggering a parking charge.
I do not know if this is true, but it wouldn't hurt for her to verify that she isn't wrongly charged for parking.
