My DH & I have APs purchased through MS but are going to buy 2 more APs for our grandchildren (they don't live with us so are not eligible for member discount). I believe I read somewhere that you could only purchase APs directly from Disney either over their website or at Guest Services in WDW. Is this correct? I don't know if it would be better to wait until we get there or order them before we go. Any advice would be appreciated! TIA.
