Ok. I called back. For us to get the $50 dining card I had to make two separate reservations. One reservations for the night of 10/20 and then a separate reservation for the nights of 10/21-10/27. At first we were not eligible for the
free dining card since we were checking in a day earlier than the promotion. But after splitting our stay into two reservations with one check in on 10/21 we were able to get the free $50 card. They noted in the computer that we had a continuing reservation so we shouldn't have to move or check out for the one night.
yay for us!
