Hi - I have a reservation through Mears to the Marriott World Center for a conference prior to my WDW trip. I am very familiar with MCO - have both rented cars and taken DME but never Mears shuttle. My questions are: Has anyone used this service recently? Are there counters on both sides of the terminal (A and B)? I have a confirmation with a bar code - do I just scan it somewhere? Are there kiosks? Or do I have to wait at the counter to check in for my reservation? Anything else I should know? Thanks!
