Its rare that it works for teens to get into the adult clubs by the main doors on the Voyager and Freedom class ships, mainly because of the beefed up security. They usually have 2 people checking cards to ensure nobody slips by. Some teens say they got in when they didnt.
It really doesn't matter what ur card looks like, they'll scan it and compare it BUT heres the breakdown on Seapasses:
M1- Under 18
M2- Under 21, above 18 (18-20)
No insignia- over 21
Dancing Shadow- Under 18
No Shadow- Over 18
2 holes punched in card- Under 18
1 hole punched in card- Under 21, over 18
no holes punched in the card- over 21
In january they got my card mixed up somehow and i had no shadow, no insignia and no holes punched in it. I never stayed in the adult club, cuz the teen club was the place to be!
I've been on over 70 cruises and its difficult to choose an all time favorite. I have favorite ships for different reasons. But my most significant memories come from the Carnival Fantasy. However, when it comes to features- Freedom of the Seas and when it comes to the best club- Carnival Glory.
