We visited for 5 days for my birthday. I mentioned this at the front desk and our check in clerk was able to offer us an upgrade for a very modest upcharge.
This was a move to a multi-room suite with a giant bathtub and shower, a completely seperate living area - really the works!
We independently looked up the rate and found it would have been more than $650 a night. Suffice to say we didn't pay anything NEAR that. Obviously this is subject to availability, but we were very happy with our stay!
