We will be visiting WDW in December, staying at the Beach Club. We need to get a GAC for our son. Last time, we waited until our second day (big mistake!) and got it at the Guest Relations in MK. This time, knowing that our boys like Epcot most, we will probably head to that park first. Since we will be entering at the International Gateway, I need to know if we can take care of getting the GAC there, or do we need to go to the front main entrance of the park? If we can do it at IG, where is that? Outside the gates, or inside?
