The network meetings are offered at each DVC resort (although I'm not sure about VWL yet). They are hosted by the sales staff and provide a nice overview of the entire program- with emphasis on the exchange features and opportunities.
The meetings include a continental breakfast and a brisk presentation- flavored with door prizes and little surprise gifts to those who participate in the discussions. They last about an hour. (They are NOT a sales pitch, but there are CM's there able to assist you with an add-on- if needed!!)
At OKW- Tuesday at 8AM, at BWV-Thrusday at 8AM- both at Community Hall. At VB and HH they are held in a GV (I don't recall the day or time right now!). Enjoy!
