I also got the 10% and $200 stateboard credit, but with a little bit of a hassle. They kept telling me to wait for a 25% off voucher in the mail and then finally I said "there is no 25%, but there IS a 10% and $200 credit offer", that wasn't offered on the cruise because Donna was busy doing other things. Then she spoke with her supervisor and I got it.
Tell them you want your 10% off and $200 credit because you weren't able to book on board.
Wait for the morning, I always rather deal with day people.
