FWIW - it would be nice to know which European property the OP was referring to, so that others will know they can only expect suite upgrade if they pay for it. I know the Prague Marriott is like that (they will not give free suite upgrades; only paid), but I've stayed at other European FS properties that have upgraded for free. So it's good to know in advance if we're going to encounter one that is a paid only suite upgrade, so we can make knowledgable decisions re: where to stay.

Cheers.
