Personally, I'm much more interested in the prop party than any con. That's not a consideration where I'm concerned, but I appreciate that it is for others. I'd just as soon skip the con as I would go.
A couple months ago I started dating a teacher, which means I get Spring Break again in a manner of speaking. Since she's off for a week, I'll be taking vacation time myself and we're going on a camping trip. The 17th is the week end after Spring Break, but we may be using that as a travel day. So March 9-18 is very questionable for me regardless of conventions, fan-days, or any other activity. I do appreciate that those events will bring some out-of-town RPFers who might not otherwise be in the DFW area.
