I have met quite a few DVC folks from forums on the Disboards. It does seem easier to meet with people on the cruise board, cruise meets, however.
In the VWL groupies thread there is often a meet in December, and sometimes posters there find they’re going at the same time and they meet for a meal. I’ve done that.
Another good time for meet ups is if the DVC Member Cruise goes out of Port Canaveral. There’s usually a good showing at TOTWL the night before. That’s not happening this year or next, though.
Good luck to you!
