I believe you can camp in the infield if you are into camping. Camping equipment are not that expensive in Europe either. And if you have a bike it is best you sleep next to it with your foot handcuffed to the steering neck, although I hate to see you with a wooden leg!
If you do have a bike and stay in a hotel make sure they have off street secure parking. Italy is the most notorious of EEC countries for car/moto theft. So next time you see a picture of Russia and nice cars and bikes around you know where many of them came from

If you are a shopper go to Imola and shop.
