I don't know about the 12 & 12 but it's my understanding that the only requirement for AA is a desire to stop drinking so I would say yes, you can go to any meeting you want to if you want to stop drinking (though if this isn't true, please correct me!)! My first foray into the AA world was a year ago and I went to several meetings a week for a month and in that time I went to Big Book meetings, speaker meetings, 12-step study meetings, open meetings, closed meetings...you get the picture
