You can call Disney Travel at 407-W-DISNEY and, simply, ask if there is any code attached to your name. You can also ask that they check your husband's name. They can check it for you right then and there.
You can also get them to give you a price quote. If you think that the quote they give you is something you might actually talk your husband into taking, then get them to go ahead and book the vacation. You will have fourteen days to put down a $200.00 deposit for a package or a deposit equal to a night's stay if booking a room only reservation.
If they do not receive your payment within fourteen days, your reservation will be cancelled. If you book the reservation 45 days or less than your arrival date, you will be required to pay the full amount.
If, after you have booked the reservation and you have made the deposit, and you find a general public code out there, you just call Disney Travel back and ask them to apply the code to your existing reservation. They will make the adjustment to your reservation.
I have found a special offer after having booked our package and I just called Disney. They applied the code and I saved over $350.00!
