When we arrived the escalator from railway concour...

When we arrived the escalator from railway concourse to the Sofitel lobby wasn't working. My partner unable to ascend such steep stairs so we had to rely on the friendly services of Qld. Rail staff.
This lady contacted Sofitel lobby staff by walkie-talkie and arranged for us to get the service lift to the lobby.
We had to wait a full fifteen minutes for this to happen.
Can I suggest a notice be placed near the broken escalator advising disabled people to ring the lobby staff to arrange the service lift.
Incidentally - Why has the escalator not been repaired? Informed by staff it hasn't operated for 3 WEEKS.
