Wednesday is when Andrew, Snow and I (and DJ?) are going to be driving down. I highly doubt we can swing leaving a day earlier. That'd mean Monday. And given that Snow is leaving on Wednesday, and we're going to San Diego Tuesday night (probably), that makes Monday kind of unappealing.
I'd say we're about 50% for going to the theme park. I'll go if other people really want to, most especially if it's Disneyland, but I also want to have the time with Andrew's family and with my friends in SoCal and it'll partially depend on how that shakes out.
