That area of town isnt the greatest, so you may not have much luck unless you find someone traveling.  

Too far from town and concerns about LE are the biggest reasons I have heard

Sorry I didn't see this in time to help out. I sometimes get crazy turnarounds @ ATL, like 4 hours in the middle of the day. Too short to sack out. I am not really much of a nap guy, so I'll book a 'day' rate @ one of the Gateway hotels. They are 5 minutes from the terminal on the ATL Skytrain. No shuttle hassles, very convenient.  
When I get such an assignment I drop an email to Sunny @ private playmates the day before and she always sends someone fun to help pass the time. She's a good lady to know in times of want.... Just for future reference: AC & Springhill have $99 walk in rates 9-6 if your a Bonvoy member and they have availability. Marriott Gateway and Renn have similar options but cost is higher. Since it's a long trip for the lady I always book at least 90 minutes and offer to cover the Lyft cost.

I provide outcalls to airport hotels for visitors~ Madison
