"Poor Signage at Night"

We had to do a complete circuit of the hospital to find A&E! There's one sign pointing you in the general direction, then nothing. As A&E is on the left, it's not easy to see in the dark, there's a sign to say Ambulance only, but nothing to say pull over and unload A&E walk in patients! Then all signs stop. In the dark and twilight it's impossible to navigate the site. And the Yellow Car Park is a mess, on a curve with poor surface and faded lines, and with temporary road blocks and very poor signage! Please walk around the site, drive around in the dark, and imagine you are half asleep and stressed out with worry and sickness. Please make the signage clearer. It's not just Ambulances that need access the A&E!
