If you are talking about a group of
DVC owners that talk amongst themselves about concerns...discussion forums such at this is about as good as it gets.
If you are talking about having an actual represenative as a liason to the DVC board...no. DVC owners have no actual vote, but the board does seem to take into consideration the desires of DVC members when it can, and if it is to the benefit of Disney. For instance, the discounted AP was something many members wanted for a long time, so we know they had a lot of requests for that from members...and it also benefits sales of DVC. Remeber that often the "salesmen" of DVC are the existing members, so I do think they try to keep us happy...but everything has to be negotiated between WDW and DVC. And discounts have to be "reasonable."
