Well, I finally found a hotel that was unable to process my gift cards. It was the Protea Stellenbosch in South Africa. Apparently, they are waiting to be registered into the program.
Unfortunately we decided to check out a day early (last minute decision as the weather turned bad and we decided to go back to Cape Town), so I broke my own rule of not waiting until last minute to pay the bill. I got the FD Mgr’s card, but I doubt I’ll bother to do any follow up as I was only there 2 nights on rather inexpensive rates.
I had no issues with the Westin Cape Town where Clarissa pleasantly processed 3 gift cards for me (2 of them had small amounts left on them).
