I suggest a hotel as a hungarian. I’ve never tried campings, it could be good fun, but as you mentioned, I’m not sure about the hygene facilities. A hotel is definately more comfortable.
I cannot mention any particular places, but try to search some “Zimmer frei”-s in the city of Mogyoród – which is the nearest place to Hungaroring. I guess there are some cheap ones too – and maybe you could take a walk for the track, if you find a nice place. (cut cost on taxi)

They are the expression of ones personality in my opinion. Its so nice to see drivers use the same design through years. To be honest I don’t like Vettels method to change the design from race to race. What do you think?
