If you check out the play now page (play.clubpenguin.com) they have member advertisements, but the advertisement changes every time you see it:

I think they are corresponding the member party with all the new member stuff. Including new member things, if you are a member, look on your player card to see you are a member! Although others cannot see it now, the Club Penguin Official Blog says that they are planning to make it visible to others. I know that some people like to dress up as non-members so that they aren’t being told to get out of Non-member parties, and being told its not fair and etc… But on the bright side they also said that they were planning special member only activities for this year! yay! And for non-members when the party is over you can play the new game solo, but members can play the other features.
