Feel free to ask, but it will come down to two factors: (1) how good your concierge is, and (2) how receptive the property is to such requests, if your concierge makes one. The former varies wildly by concierge, and the latter by property. Other than anecdotal data points from people who share the same concierge as you and have had them make a similar request at that property (which I expect to be few and far between), I'm not sure if any other info would be useful for your situation.
