Same Question. Me & a friend are flying over from the UK to Budapest. Two options are:-
Camping near circuit or in a hotel in Budapest, both cost the same!
Camping Pros – No Travel Hassle, Good Atomsphere.
Camping Cons – Expensive, questionable showering & toilet facilities?
Hotel Pros – Clean Shower & Toilet, Good nights sleep!
Hotel Cons – Less Atomsphere, Travel Hassle – 1 hour trip via free bus.
So got to make a decision. On the other hand I have Super Gold tickets, so I got a special parking pass, so anyone driving from Budapest to the Circuit that has space for 2 could be an option or maybe splitting a taxi fare!
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)
