When I stayed there last month, I was told the breakfast as the platinum was only the continental breakfast, and pay to upgrade for full breakfast.
I was not sure they checked what I got from Buffet table, but I just picked continental items from buffet table(which was sufficient enough).
Maybe, I was misinformed when I checked in

- We also stayed about a month ago (Aug.18-19 to be exact). I was told that PLT gets a continental breakfast for two and that upgrade to full buffet is 6 Euro (I hope my memory is right!) per person. We took an upgrade and indeed I was properly charged at the end.
