Hilton Riverside to Julia St. Terminal

I know it's been asked before and I've seen the threads and the video on the walk from the Hilton Riverside to the Julia St. terminal, but I still had a few questions. After you do the walk, how do you check your bags in? Where are the porters? It looks like the elevators take you to the check-in area.

Thanks.

The porters will be there (or close by) when you get off the elevator.
