Everyone is going to get these cards in there packets but I wanted to give everyone a sneak peak. Check this website for details. I hope that this helps someone.
There will also be a savings card for the businesses located in the food court attached to the hotel in the welcome bags too. You should be able go the show and not pay full price for any meal is you use the 2 cards.
Have received discount cards for the welcome packet from Johnny Rockets. They have 2 locations near the hotel with one being in the Atlanta Underground.
