Protea Hotels a blot on the good reputation of Marriott.

Wont go into too much detail here but after a very bad experience some months back at the Balalaika Hotel restaurant in Sandton my wife and I didn’t return there for months. We went back for lunch on 31Dec where they declined to honour a Prokard discount ( I’ve been a Prokard holder for decades) on the grounds that it’s not valid on New Year which I was aware of but this was the day before. I cannot find any notice on their website to the effect that they consider the New Year holiday to commence on the morning of 31 December .They are a shame to the Marriott Group
