While I would not urge
DVC members to make a special trip just for the Annual Meeting, IMO, it is worthwhile if you will already be there. The actual BOD meeting(s) are tightly scripted and typically last only a short while. They involve the Board members approving the annual dues and any other proposals. Regular members are not allowed to ask questions or vote since we have already ceded that right to the voting representatives for each DVC resort (sort of like the Electoral College).
There has usually been a theme for the meeting, often with entertainment (last year the MK "Dapper Dans" entertained - the first time so many had performed at one time ever). After the board meetings, resort managers are introduced and each offers a brief overview of the past year at their resort(s) along with what is scheduled for the coming year. There is normally a Disney corporate presentation with what's new at Disney followed by an invitation for those in attendance to ask questions and make comments.
Some years the event has dragged on especially with the questions but the board and resort managers will stay around afterwards for individual questions.
Well worth attending if you are already there. We have been to about 12 meetings over the past 19 years.
