S.B.
I have never caught the shuttle to the train. I am waiting until they have a TRE train stop at the airport which is not scheduled for a few years. If they are bringing luggage, it will be very inconvenient. They would have to take a bus from the terminal to one of the long term parking locations and transfer to a shuttle to take them to DFW Centerpoint. At that point, they would board a train and take it to FW. You might also consider some of the airport shuttles that pick up and deliver to some of the downtown FW hotels. The shuttles would pick them up at the terminal and take them to one of the hotels and you could pick them up there.
