Yesterday I received our AP voucher and my husband's park hopper ticket. This is our first AP. On our first day at WDW we try to get there as early as possible so we have a full day on site. Last two times we arrived and checked in at 8 a.m and 10 a.m. and were off to the parks. We are staying at the BWI this trip. I know we need to get the actual AP in hand to check in. My TA told us to go to Epcot to get it. My question is this. How early can we get the AP? Do we have to wait for the parks to open or can we get it prior to that?
