They've released some dates up to May. Which I was planning to make a trip by then.
The few dates I've picked out are
3rd-6th April (Easter weekend)
2nd-3rd May (It's closed on the Monday bank holiday. Can be used as a day travelling home)
7th May (this is an open pit lane track day at €650)
There's a few other weekends during April/May where it's open but sometimes they're not full days.
If anyone is interested and would like to come along then you're more than welcome. I'll confirm which date I'll be going on soon depending when it's best for everyone else.
If you can't make it now I'll probably be planning another trip around July/August.
