I know right, it would be nice if they would release less items at parties so that it doesn't feel like they're over-saturating the game with ugly, unnecessary, content nobody is going to use, and put their efforts into two or three items, and then allow non-members to have only one of those (maybe two during a special event), and give members the rest. And hey, just for continuities sake, let's make the non-member items hats, because everyone loves hats. And let's continue this trend for 4 straight years.

Seriously though, this is only one party every few months that they are doing this for. It's the New CP equivalent to Members Only parties, and just be happy you don't have to wait a few days before you can enter the Night Club again.
