FYI: Nightclub FAQ is done from nightli's perspective and we recommend checking with multiple sources before you decide, see answer:
There are different ways to add you and your friends on the guestlist. First step is to get in contact with either a club manager or promoter for the night club. You than send him or her you full name together with the amount of friends you're bringing to the party, remember to write on time! Lastly, the guestlist is often closed before 11pm and it's therefore important to arrive at the club before that so you don't have to pay the entrance!
Another option to add yourself on the list is to use the Nightli app and simply search on the club you want to attend and type in your full name and the people you want to take with you!
