The 1991 DS Cast Reunion committee is now accepting registrations (a limit of 300 tickets at first come, first serve, refundable if the event is cancelled, only $20 before May 13) for their East Coast event on July 27 at Lyndhurst. This is of course the day before the DS Fest begins at the same location but is a totally separate event.
The most recent update includes the above info and the attendance status of each of the 24 living actors from the revival series, plus Monica Rich from NoDS, all of which can be found on their Facebook page:
Friends of the 1991 DS Cast Reunion.
Also: Raffle of original and '91 series memorabilia and tours of Lyndhurst's tower room; photo ops in the mansion with a donation; autographed photos sold by the stars
A West Coast event will most likely take place in 2013 with tentative guests Joanna Going, Ely Pouget and Eddie Jones.
It all sounds very well organized and could be a lot of fun!
