A Happy ending.
I received the e-mail from Le Meridien KL the day before my scheduled check-in, letting me know that we had received an upgrade to a Royal Club room;
not a suite.
That wasn't delightful, as we know that the regular rooms are quite small, and if you get a corner room....
We checked in at the lounge, and the lounge attendant said, after I wondered whether we might be able to get a suite: let me check, and later said check back around 8pm.
The cocktail hour here is 6:30 till 8:30, and around 8:15 an attendant approached us with the good news that our suite was ready, and would we like to move immediately!
Thanks SPG
