I believe Hilton has some Diamond availabilty up until early summer of this year... Starwood was long gone.....
I was thinking of going there but there are no hotels available, all major events are sold out and the city is over crowded as it is... so I am not sure if it's the greatest idea to go there anymore during that time...
I mean, what is there to do - no where to stay, no events to see, even tourist attractions will be over croweded....
