We visited the Las Vegas Hilton to dine at the buffet restaurant using the prize I won from the ACG recently. The Hilton person who handled getting my buffet comp was great answering my emails and cell phone calls. The place is so big that we got lost finding a place to park until we finally found the parking garage. The buffet was actually a disappointment being so small.
(But a free buffet is always good!). The player's club was not offering any special incentive to join, so we didn't.
