Get on a Mailing List
The simplest way to beat the line is to get your name on the guest list.
One way to accomplish that seemingly impossible feat is to join email lists that regularly send out party notices; often clubs will have links to these lists on their websites, but you can also go through third-party sites like Thrillist or UrbanDaddy.
When the club wants to promote an event, you’ll receive an email with information on how to RSVP to get your name on the list. These parties usually happen Monday through Thursday, but every once in a while you’ll get a plum spot on a hard-to-access guest list, making you the envy of your far-less-connected friends.
