I was there before a queue formed but after, I would guess it was at least a 20 min wait to see the desk. From there, it was a long wait for the hotel confirmation and bus to the hotel....

It's unclear where you should wait after handing over your boarding pass and waiting for the confirmation but there is a seating area about 20 metres away near the long escalator. The staff come over and collect you from there when your bus is ready....
