Spoke to a terrific manager in a Chicago Marriott today who told me they've revamped the whole gift card processing and I noted on my folio that it was no longer coded as "Visa" (or CCard-VS), but, rather, as "Giftcard". It is being administered??? by givex. She printed out a givex receipt which showed the redemption from the gift card and, after noticing my little sheet of paper attached to my gift card where I keep a running balance, offered to check to see if she could get previous redemption information. Seems this might make gift cards easier to track....but, alas, if there's a promotion that requires a Visa card...I fear we may not receive credit as in the past. Just something to be aware of in the future.
