There needs to be discounts for people who have to come regularly of course. My local hospital has a secret way of paying for parking that only costs £12(?) For however many days you've stayed there.
I guess it depends on the hospital.
Also, I used to work at a Hospital for 8 years of my life and then crossed over to being a visitor due to my Dad, so i'm well versed in Parking Fees and they're an absolute con and take advantage of people who are already having a shit time of it (patient/visitor wise). It's even worse given I know where the Parking Money is going.
