I disagree completely. Regardless of whether or not one would personally choose to ask the SPG Plat Concierge team to complete this task, the bottom line is that this sort of request falls PRECISELY into the category of tasks that SPG advertises (or, at least, used to) that eligible members of the program should utilize the concierge team for.

I'll quickly agree that when the SPG Plat Concierge program was rolled out many years back, it was done with a fair amount of fanfare and promises. These days, I don't see much mention of the Concierge component of the program, but we've not been told that it's been diminished in any way, so my expectation is that the offering remains unchanged. If so, it was always marketed as essentially a carbon copy of the AMEX CONCIERGE concept, whereby any lawful, reasonable request would be attended to.

Moreover, in practice, the PLAT CONCIERGE team quite often did nothing more than forward questions/requests over to the local hotel concierge team for processing. Insofar as that's always been the case, they should've been able to handle a simple floral order for a guestroom within their own network.
