Parking at 8pm at the start of a night shift isn't normally an issue at Hosp as all the clinics have finished. The busiest time is 8.30 -5.30 when more people visit them.Is it bugger all at the end of a 12/13 hour day or night shift. With possibly another 30-minutes to an hour drive home?

As for free parking will mean city workers will just park there, I'm sure they could manage some sort of parking permit or ANPR for staff only??
