GRO means Guest Relations Officer and it is a term used only in the Philippines. GRO's are Prostitutes that are employed by Hotels. They are sometimes advertised on little folding cards that the hotel leaves in the room. These cards will often say that in room massage service is available. It is understood that this for an in room prostitute or GRO.
I stayed in the Manila Hotel in the Philippines and I called the front desk and requested a GRO to come to my room.
