Additional thoughts after returning:

• Shuttle was waiting at Level 5 West side, which made me feel good...
• ...until I realized it was going to then head to the East side, so definitely a delay.
• This shuttle had a U-shaped arrangement of one long bench seat inside; still leather/pleather.
• Another friendly driver. Took each of us exactly to our car spots.
• Exiting the facility was a problem. The exit is not well marked at all. The exit kiosk took my e-mail QR Code OK, but then failed to issue a receipt after I pressed the button for one. Then, the "call for assistance" button was broken, directing me to a phone number to call while I'm at the exit kiosk. I gave up and drove off without a receipt. I'll have to monitor my CC statement to see exactly what they charged me, as the amount never even appeared on screen.

So, some pluses for friendliness. But they're one of the farthest out of the parking options, and they're not maintaining their equipment well. Should I have need for cheaper parking on a long trip next time, I'll try one of the others.
