I have a theory that cast members have been instructed to say "May your heart be your guiding key". When my girlfriend and I went two years ago, we were so damn cold at Disney World (it was January, we were surprised how brutally cold things could get in that humidity) so we bought a Sora hoodie for the low low price of sixty fucking dollars at Epcot. For the rest of the trip, it was all we would hear. "May your heart be your guiding key", "May your heart be your guiding key", "May your heart be your guiding key".
One woman working at Epcot was really excited and conversed with us for a long time about Kingdom Hearts, to the point where we were kind of trying to get out but she was just going on and on about the games (Kingdom Hearts 3 wasn't as good as the others, apparently), and that made me realize that the "May your heart be your guiding key" business might be a way to get employees to yap less about Kingdom Hearts and acknowledge it in seven easy words.
