I think the public code is YMP. It may be possible that disney only made a certain # of those available and if they're sold out for your time, then you may need to go back to your email to get your private code. I'm guessing that even if the public one was sold out, they maybe had a different allottment for the private onese they sent out before offering the public one??? Does that make sense? Really, I'm just quessing, but that may be why she was asking for YOUR code.
