But why are these things so often scheduled for weekdays?
Conference fee? I'm sure it will be fair.
Plane ticket? No problem.
Hotel room? No big deal. I'll just make it a vacation.
Monday and Tuesday? Deal killer. There will be too many phone calls, emails, and support requests to miss.
I bet that most of the people who would best take advantage of this conference don't work for large companies that will send them. They have to slip away over the weekend and get back to the office Monday morning.
Startup School does it right. Fly from almost anywhere. Catch every event. And make it back to the office before little problems have a chance to get too big.
