HI GH Dallas. I was on your cruise as well. Actually Celebrity explained in their first "Celebrity Today" paper that those meetings would not be posted in the paper, but on the activities / message board on the ship. I think they printed that article again later in the cruise.
Celebrity made this decision a few months ago as they were receiving a lot of requests for special gatherings for "special interests". The only other meeting group I noted in the daily paper was the "Freinds of Bill W".
I loved the cruise, we had a fabulous experience - especially on the heels of a Princess cruise taken in April, where there was no compliance or attention given at all to FOD.
I will be writing a review of our cruise and posting it later this week!
