I just received an email for Lounge Club members. This offer allows current Lounge Club members to bring a guest for free when visiting The Club at LAS. The offer ends on July 31, 2012.
I am only a member of Lounge Club because I have the Ink Bold credit card from Chase. This card has an offer where I can join Lounge Club with no annual fee and it will cover my first 2 visits. After the first two visits, I will be charged US$27 for myself and any accompanying guest each time I visit a lounge.
