The LVH (probably best known as the Las Vegas Hilton by most visitors) has been bought by the Westgate Resorts timeshare company and is now the Westgate Las Vegas Resort & Casino.  Many of the rooms and suites will be converted to timeshares, but it will still offer a selection of hotel rooms for conventioneers and casual visitors.

The LVH Players Club will be rebranded as the Westgate Las Vegas Players Club, but your account and points should carry over.  No changes to the players club have been announced other than the name change.

You can read a bit more in the Westgate press release.
