I've been there last year, it is a nice spot on the land with a fire place, Basketball court etc. Last year we all had to pay i think 10 or 15 euro for a bed, maybe 20 i cant really remember. You can come spontaniously there is enough room for everyone. Invited are ROTLA Rare and some randoms i think
the organisator asked for a official confirmation if ur coming or not.
I will be there whole weekend. People will probably arrive around 16-18:00 CET on Friday 02. and end is morning of Sunday 04.
there will sure be room and beds enough, but u should bring bedstuff or a sleepsack.. i guess we will be around 20-30 people, can be fun! count 20 euro for a night, i dont know for sure how much he charges but definately not more, if u bring tent u ofc dont have to pay.
