Sweet 16 and the memphis peabody.?

Alright so this november i will be tuning 16. I wanted a sweet 16 dance party and i thought what better place then the peabody? I was wondering if they had any rooms that were suitable for this (and i know its crazy) but could you rent the rooftop for a night? Also how much would a room be for one night? Lastly if the peabody is not an option, what other places would be awesome to host a sweet 16 at?
