Mike is right - every since we started sailing with HAL in 1981 there has always been a "Friendss of Bill W" meeting on all the HAL ships we have travelled on.
After a few cruises we noticed that this guy "Bill W" was always on the ship with us and we wondered who he was so we asked the CD who he was and to point him out to us.
Brian Pryce went on to tell us the signifcance of the "Friends of Bill W" meeting..... boy did we feel stupid.
Brian said he had started the meetings on the ships a few years back and they were very successful.
Good Luck and have a wonderful cruise.
