We have had friends visit us at FW on numerous occasions. They must park in the FW main parking lot (where you check-in at). From here, they can either can get on the bus that picks up right by the parking lot or you could drive up and pick them up at a designated time. We have tried both, and the latter works the best, as FW is huge and is very easy for the novice to get lost in. My recommendation ...... set up a time with your friends to pick them up at the main parking lot. You can either all ride the bus together or go in your vehicle.
