I will be visiting these cities in February over 17 days in total and I'm hoping to meet up with explorers to show me around the best your city has to offer. If you ever visit South Korea I will be happy to do the same for you.

Belgium here. Send me a message with the dates you'll be around.

Cool. I will let you know when everything is confirmed, hopefully by the end of next week.

Finally got the visa sorted out.

Forget about Rotterdam and Amsterdam for urbex. The only thing I can think of is the old Hembrug ammunition factory in Amsterdam but it's being redeveloped. Don't know if there are still buildings left abandoned, and if so, be prepared to fight your way through crowds of tourists and hipsters to get there

Damn. Nothing outside of the cities either? I'm open for anything, really. It doesn't have to be a medieval sanitarium or anything super spectacular; basic abandonments will do.
