[Oktoberfest][1] is the world's largest beer festival held annually in Munich, Germany. Being the largest beer festival means accommodation during the festival is either super-expensive or hard to book within a short notice. [Showers](http://travel.stackexchange.com/questions/48719/public-shower-options-in-munich),  [food](http://travel.stackexchange.com/questions/48759/breakfast-places-in-munich-that-open-at-6am-or-earlier-on-the-weekends) and [beer](http://travel.stackexchange.com/questions/48724/how-early-should-i-get-to-the-oktoberfest-tents-to-get-in-without-a-reservation) are available without reservation, so a place to sleep is the only problem.

My friend has a small minivan which is convenient enough for sleeping. Would it be legal to find a quiet parking space somewhere (relatively) close to Oktoberfest and just sleep in the van? Bonus points for recommending a good spot to park in that area.
