Never been on the ring?
Just do it, it's loads of fun. Even if it's for one lap.
Just don't get in your head that you'll set a fast laptime or something like that, the first thing that'll happen is that you'll be overtaken by someone in an old ratty fiesta or so that is completely stripped on semi slicks. That said the first car you're overtaking might just as well be a ferrari or lamborghini

The difference in driver experience is huge there, nothing like a track day on a normal track so that takes a lot of consideration.
The whole atmosphere around it in the villages is also great. Go to a supermarket or so and see a group with 20 lotusses or so parked in front. Dead normal there. It (the whole region) just oozes motorsports and car fanatism. Much more that other big tracks (like Spa for example)
