costs 39 EUR and is valid for one day / 5 persons, so only 7,80 EUR for everyone

but the journey is a bit longer, between 3,45 - 4 hours.
dunno yet how many we are, but i'll keep you informed here. there is no advance-booking needed for the weekend ticket, price stays the same.
EDIT: just realized the gig is on a saturday, so weekend ticket can be used even for both ways. makes less than 16 EUR for each traveller (return). sounds good, eh?
