Not sure where you made the connection from sorry Rwylin that the nightclub will close at 11pm? The bars are independant from the nightclub, and run by the Hilton staff. They will not serve alcohol to anyone beyond 11pm if you are non resident. How they implement control of that is down to them. However, without looking at the event schedule to confirm, my assumption will be that, as per year on year, the nightclub will close around 2am.
There is a bar that is exclusive to our event, the Millers. However, the same rule as above applies. That said, I suspect it is highly unlikely that they will refuse to serve people whom are obviously part of our event, resident or not. But the policy remains, and again, its up to them how they execute this.
Hope this clears things up?
