Due to the trams, they've moved the courtesy bus stops from next to the terminal, to a 5 minute walk away, close to the car rental terminal.
It may seem a little thing, but when you're tired from travelling and just want to get home, and it's cold and wet and raining and you're lugging bags... that extra walk is really something you could do without, particularly if you might then have a wait in a pretty exposed bus park for your bus
I so wish the airport would stop doing things to make things more difficult for people not coming in by public transport or taxi. I don't always have the 2.5 hours travel time I have to allow if I'm coming in by public transport (when it takes 25 mins to drive!)
And from where I work, there aren't any public transport options...
