For those who have taken part in overnight stays/dinner courses/appts for more than a couple of hours, how do these rate against your standard 1-2 hr. appt? I'm asking because it seems to me like, if you do the whole overnight thing, you only get the same amount of time as a 1-2 hr appt due to the whole sleeping situation. Just doesn't seem so efficient at first glance. I like the idea of a dinner course though, because I like to chat like crazy. Thoughts?
