Meetups on each day (or even on just two days) sounds like a good idea! Especially since people have other meetups, and if they miss one they can just go to another on a different day. And Homestuck cosplay has been a big majority at cons, so maybe this way the groups won't be so big and clustered. Noon also sounds good, since not much usually happens around that time.
Unfortunately I have a meetup on Saturday around noon already, and I might possibly have one on Sunday around that time. If we end up having a meetup on Friday, I'd be happy to try and take charge of it, unless there's someone who wants to and can go to more of the meetups.
