I'm rather tempted. I'm funemployed at the moment and live over in Stockholm so it's just a (long) train journey away. I used to enjoy messing around on Vaxen in my college days.
I can't see myself ever using VMS professionally though, and it has a somewhat vague description of the actual content. It's not super expensive but I'd have to fork out for the travel and accommodation.
I'd love to hear about it if anyone does a write-up after the fact.
