Good News! I spoke to my contact today and he said that if a fellow arrives after 2pm, they can pick up their guest pass at a different kiosk. You wouldn’t be able to pick up passes for anyone, other than yourself.
The closest Kiosk, which should be open until 4pm on Saturday is at the corner of Westholme and Hilgard. See map.
Once they pick up their pass, they can proceed to lot 4 and park.
Thanks!
