Just stayed at the LV Hilton. I believe they have a new theme there: Expect nothing and you won't be disappointed.
I've only been a Diamond for a couple of years, so what are the amenities? You get an upgraded room (that's new tile in the bathroom), and we'll arrange for a USA Today to be delivered to your room (he arranged that on checkin, but I'm still looking for the paper), and you get the bonus points. I've stayed at all of the Hiltons in town and, with the departure of Bally's and the Flamingo, now I'm gone.
I tried the DoubleTree on Warm Springs (apart from its proximity to the Strip and absence of a casino) and the standard of service and follow through was outstanding; I found a new home.
