We go to Vegas at least once or twice a year and have stayed at many places. This honestly was one of my worst experiences.
They have zero cocktail service for starters. They don't accept comps for drinks either. They reduced the slot game space to put in a night club. The shower pressure was way to eco friendly (lacking pressure). The upgraded room had paper thin walls so I got to listen to some gentleman's strip club booty call story.
We complained to the pit boss about the cocktail service. She apologized and said we were not the first to complain. The next day we talked to Sal the assistant manager who was upset that the pit boss told us to complain to him. The end result was a complaint form that we could fill out. This is no longer a Hilton property and is owned by Goldman Sachs which explains everything. The only plus was the Big Bowl party which was actually well done.
