Well,
at the moment there is a 50:50 chance for me to make it.

either I come with a friend, but he refuses to stay at the hostel and prefers camping (which is out of question for me)
or
I cannot come at all cause I don't have a car at the moment and don't know how to reach it with public transport

Or
I have a car, can come up by myself and stay at the hostel...

sorry, I cannot be more precisely at the moment :-(
