Went to work late and to make things worse, I forgot my watch.
I am posting this at about 8:06PM and my watch has 0 floors and less than 200 steps.
Bottom line a got a LONG, nearly 10k step way to go and I got less than 4 hours to do it. Pretty sure I can.
I am predicting I should be back home in time to edit this post, but posting early just in case. I am going to walk concourse A to D and see how many steps those are. If they are not enough, I am doing a normal loop around from my work area to light rail to car.
Update: Made it on time, it was 5k steps to start from the S entrance near A and all the way through A B C and D.
