ChrisUS...If you're interested in an Admiral's Club membership, I HIGHLY recommend getting the Citi Executive World Elite Mastercard, which gives you a Club membership plus a lot more.

It has an annual fee of $450, which is $50 less than getting a membership directly with the club, plus you get 50,000 ADV miles. They'll also reimburse you $100 for a Global Entry application.
You can bring in either 2 guests or all your immediate family members. In addition, every other Authorized card holder on your account gets Club access as well. They're not members...but you don't have to be with them for them to access the club.
One other cool thing, when you travel on ADV miles or purchased ticket, you get to use the Priority Access line.
