Confirmed nothing.
I know I'll be in NorCal before the con! I know we'll be driving down on Wednesday, July 10th! I am planning on staying longer in SoCal after the Con, but the dates are flexible. Still planning on going to San Diego during SDCC, then driving back up to NorCal on July 21st or 22nd.
At this point: Con is as good as confirmed. Pre- and post-con are flexible, depending on who's with us, Andrew's and my job situation come July, and what people want to do.
If I had to guess? We'd do the "theme park" stuff on the Thursday before (July 11th) or Monday after (July 15th) -- that really depends on how we're arranging getting people to and from the airport before and after the con, and who's interested in going, and to where. My preference is for the Thursday before.
