@ricnorrisf1 if you want to stay at a hotel/airbnb it might be expensive & you might need a car but if you're fine with camping it costs 250-270 for 2 people for 3 nights (price per person gets cheaper the more you are)
@ricnorrisf1 bit biased since it's my home race & i've only ever been to this one but: austria. tickets range from 150 to 660 (but i don't think the 660 (main straight) is worth it anyway). easily reachable by train from vienna. very well organised imo
