Add the LV hilton to that list, albeit I don't believe quite as bad as Reno. I too am curious why these PP Ent. Hotels can use the Hilton name if they are not properties of Hilton nor participate in the awards.
I would fire off a letter to the CEO, cc adam burke and the management at the property in question.
I won't go back to the LV hilton, I'll stay at the ES which are great, or the Marriott.
