We're trying to squeeze as much of Seoul as we can into our 4-day schedule. It'll be hard to commit to the itinerary but it's worth a try. This should be much better than just going with the flow and wasting time while we're there.

Are we too OC? Yes? Oh, well.

Anyway, I told Katia that on each day, if we get everything done early, we can return to places we've already been to should we want to re-visit. This should really not be a rigid schedule. And as much as I could, I made sure that places we need to visit on a per day basis are adjacent to each other to avoid wasting time in trains and buses.
This is probably the best itinerary I can come up with at the moment. Although I'm quite certain that this is pretty much subject to change.
