Hey, I'm in Seoul for business on 24th and 25 July. I'm thinking of staying a few extra days to see the place as it's not somewhere I doubt I'd get to see otherwise!

So how many days do I need to experience the main culture and attractions? It's a shame the DMZ tour is currently closed as that was the main thing I wanted to do.

What else? Trip to Jeju island worth it for a day trip?

Thanks!

Jim
