new Hilton brand standards

As you may have seen from the Canary Wharf Hotel thread - apparently there are new Hilton Brand Standards. Speaking to staff at another property I also was taught about this, but no details sunk through yet. What appears to have become possible though is to close the lounge earlier on weekend nights (even though a number of properties seem to have always done so).

Anyone filled in on some more details of what these new brand standards may bring - I guess it will have been termed an "improvement"... ;)
