We have a podium that we set out in the lobby in front of the doors. 

Our volunteers are stationed at the information desk, alongside the paid-staff guest ambassador.

Mine is the same as Reina's. Ours are Information Desk volunteers and most of the time we have 2 or 3 stationed there at the same time. I have a chair outside of the Information Desk, with the intention that it be staffed with a "runner," but I can't keep that position filled. Everyone gravitates to behind the desk.

Ours are called "PathFinders" .  The PathFinder (volunteer) is located at the Information Desk.  The Information Desk is manned by one paid staff (registration) and one volunteer that answers the patient calls, transfers calls and answers questions. The PathFinder stands, up and ready to greet and assist with a wheelchair or walk side by side visitor or patient to get them safely and with ease where person is scheduled/or wanting to go. We do have a chair for the PathFinder.  The chair is pushed neatly under the desk when no in use.  At times the PathFinders sits, but that is limited.  We tried not to have a chair, but with the volunteer working 4 hour shifts at a time, it became difficult with no rest period for tired legs.
