What you are asking is a bit unreasonable.
Those rooms are likely booked a year or so in advance and cost top dollar.
If I were you, I'd be happy just to even get award availability those nights in the hotel to begin with - usually for extraordinary events like that (e.g. Superbowl) they don't have award availability and won't even honor the 48 hr guaranteed availability if you wanted to book a room w/ cash.
