So was it one of the DVC presale appt guys who asked you that?
It seems like it shouldn't even come up until you are preparing to sign papers with legal at purchase.
I am honestly astonished. I am genuinely curious about the purpose and necessity of that information.
Hopefully someone will know and come tell us.
I bought direct from Disney, sole on the contracts, but am married. They asked no questions that I recall, It was back in 1995, about my marriage. I simply made this my purchase, one person, on the contract. I didn't have to explain. I really don't recall any invasive questions. But as I said, that was back in 1995, and my memory and eyesight have both dimmed. I bought more direct from them in 2010, and no questions then either.
