Door 507(Southwest) on the east and 508(United) on the west. They pick up at island 5 right out door 507 on the east side.
Green Ride drops off curbside at DIA on both sides of the main terminal. On the West Side we drop off near United Airline's curbside check in between doors #506-512 and on the East Side we drop off near Southwest curbside check in between doors #507-511.
I found it important to reserve space to/from Ft Collins if that is your destination. When I took the shuttle 3 weeks ago, there were folks left behind because the shuttle was full and they hadn't made a reservation
