Great track, it is used more for Bikes these days as its not the widest but it is great fun to drive, lots of up's/downs and tight corners.
Advise
1/ Fill your tank up with fuel before you arrive (there is a shell garage at Louth not far away)
2/ Take cash with you (If you want food / tea coffe etc and crash helmet hire (if you dont have one) is normally cash only)
3/ Format is
Sign on - you will get a form to say you accept if you have an accedent you cant claim from them or any other driver involved even if it is there fault.
Get yourself a crash Helmet (if you dont have one) you are limited to real bike or car helmets, if the car is open top then full face one needed.
Get the car sound tested - easy job you just rev the car as high as you can and they take a noice reading (if its to loud then they wont let you on the track but stock road car you should have no issues.
Then there is the safty briefing - listen to what they tell you its for your saftey
Then you have a sighting lap (when I did it there were three groups but they use teh tannoy systme to tell you who is going out, the sighting lap is just a gentle drive round the track so you know what to expect when you go out and can see all the marshels (who will advise you if there is a
problem) - this is normally around 09-00 then they will call your group and you will get something like 20 minutes to drive around the track.
If people are up your back side trying to make you go faster than you want, if its safe to do so pull over, if not they have to wait dont put yourself at risk.
Then the chequered flag will be shown this means that this session is over, you can come off park the car up.
Open the bonnet to
help engine cool down, do not apply the hand brake as your disks will be very hot just let them cool down and before you go back out again just check your tyre pressures.
Enjoy the day
If you go on Youtube you will see lots of video's of peoples track days and its worth a look to get used to the track.
Keep an eye on your fuel level, normally I go back to the garage to fill up at lunch time but it does depend on how much track time you get and how fast you push it.
If you come off the track you will be told to come in, this is a simple safty measure to stop you having a more dangerous accident and let your addrenalin cool down.
Then before you know it it will be time to go home and you will be very tired as you concentrate a lot .
There is normally a track instructor you can hire (not a huge amount of money) and if you can afford it I would recomment it as they give you good advise.
There are a few flags which tell you to come off / slow down this will all be explained in the safty briefing.
Have fun.
