I think you are diamond, though?
As a new Plat (Accor-Plus), with 21 nights over 17 stays booked in Australia and Europe in the next few months, I'll be watching the early check-in, upgrade etc tally very closely.
I was thinking of e-mail each hotel a few days before arrival, reminding them of my room preference and asking for early check-in etc; does anyone thing that will do any good?
