What's a typical price for an upgrade at the Poly?

I've seen some post about upgrading to concierge for about $50 per night extra? Would that be the same price for an upgrade to concierge at the Poly?

at easter it was $80 plus tax a night, we did not take it because it was a garden view, which we were staying in anyways, if it was a lagoon view then i would have done it.
