What is the difference between:
Porter service till chauffeur service point
Porter service from terminal till chauffeur service point

I'll be traveling DFW ---> DXB, so I'm interested in their arrival service, and definitely want porter service to where the Grosvenor House driver picks me up.
How do the words "from terminal" (the Elite service offering) make those 2 Marhaba features different ?

In either case, we'd be walking from the terminal to wherever the driver pickup area is.
Right?
