I noticed one minor nit on the wiki that probably will make no difference at all. The wiki says to take the #9 bus designated 'University'.
But the travel planning sites say that the #9 bus from Hengelo will say 'Enschede' (it passes the University on its way). The buses probably say both, but figured I'd mention it just in case...
Hopefully, I've confused someone else enough that I won't be the only horribly lost person on Friday.
See you then!
Cheers,
Jeremy
