Mine is a 15-minute walk or 5 minutes in the car, depending on traffic (could be less at 2am or more during the day).
We're probably going to call a taxi though because parking is terrible at the hospital, at least it's unpredictable (and expensive), and I don't want my OH to be stressing about it. The hospital is one of the few high street hospitals left, so there's no room to be building big car parks.
