On a trip through The Far East, and mixing Sofitels, with Novotel (new at BKK airport).
Upgrades always done when i arrive, with wine, and fruits or chocolates ready. Room requests met, appears some of the best rooms allocated.
Club benefits / access at Sofitel are always given wherever i go.
It is important though, to book through Accor themsleves if you have the Le Club Accor Gold or Platinum card, and the system alerts staff wherever you travel.
I find that the benefits of any hotel card are for your actual stay itself now, not on points any longer, and never on free nights. I convert points to miles always.
In this regard, the Accor groups is the most consistent, at every level of hotel in their group worldwide.
