I'd love to go over to impakt festival and stay in Utrecht for at least one night, so I can visit the festival for two days. I'd offer 6 hours per night, accomodation can be something really simple, I don't put high expectations on it. A living-room couch or a simple inflatable matras would be already enough!
The dates I'm currently aiming at are 26-27 october.
all the best
