The 'good' folks at Wilson Parking manage the paid parking at Palmy Hospital. I feel sorry for any residents within about 500 metres of the hospital as lots of people park in residential streets to avoid paying.
Which is why the nearby residential streets are a mixture of "residents only" permits and 60 to 120 minute limited zones. And from what I'm told by my family, very heavily policed and ticketed.
Some streets are, but there is still a lot of streets around the hospital where we can park all day without paying for it, which is what I do for the 1-2 times a week I might bring a car to work.
