When I started sanding the table, I thought "ooh, look how much I've sanded in such a short time. I'll have this finished in a few days!"...
I reckon I've done three solid days of sanding, and the surfaces of the table are pretty much all flat. The chairs, on the other hand, are all curved and turned surfaces. I reckon I'd be looking at about a week per chair, and a few of the joints are a bit loose, so, knowing me, I'd probably try to dismantle them completely and rebuild them. It's a daunting prospect.
