I typically sanitize in iodophor, stack on my bottling tree and then begin bottling. I've not tried to break things up, but see where that could be more convenient. With my schedule, though, I'm usually bottling during the week and brewing when ever I get a free Saturday or Sunday. My two teenage boys really monopolize the weekends with sports, scouts, etc. So, even though it's a longer sessions it is the time I have available. maybe I'm just getting quicker with practice.
I'm starting to like the oven idea a lot.
