Just stayed there last week. We used to stay at the AUS airport Hilton which was also a very nice property.
Since we only had 10hrs there it was a brief visit. Lobby is unreal. With plenty of checkin people standing there. I hate to wait in lines.
The buisness center was awsome. They have wireless throught the hotel. You can see the routers on the walls when you walk down the hallways.
I swear nobody ever stayed in my room it was that new. They also had wired connections for high speed another nice touch. We checked out at 4am and there were people downstairs. They even ran to go get me a newspaper for the cab ride to the hotel.
The restaurant was new and there was a ton of things to do right next to the hotel. I've got a friend who told me. Didn't have time to go out.
Stayed at over 200 different hiltons last year and definetly rate this one though the roof. An excellent property should be a 5 star.
