The rental service is called Mein Zelt steht schon. I reckon they'll be announcing any news, rates etc soon enough. Just keep an eye on the news.jaja, thank you "thesubtleknife".
I have one camping question, i bought 3-Days "ALL IN" Ticket W:O:A 2018, i believe this is with camping access right? should i re-confirm my camping place?
what do you know about tents renter? is it recommendable? because i am going to take one for the 3 festival days and i believe is too expensive pay 100 euros for it... but how i will be traveling around 1 month in europe.. maybe is better rent one and not buy a new one and carry it for all the my trip... its not very confortable
thank you!

), our tents were in a decent spot about a 3 minute walk from the Mein Zelt booth. Only problems that we'd have is that whenever the occasional downpour came through the wind was strong enough to pull the stakes out for some of the tarps. Speaking of the tarps, depending on how they tied them down, you may find yourself reenacting "Indiana Jones" trying not to trip over one while stumbling back to your tent!! Besides that, they were usually pretty quick to get someone over to give you a hand setting the tarps back up.
