Appreciate the response Rachel, thanks.
I also checked the Circuit’s website and there’s a lot more info there than a month ago, or i was blind a month ago, both possible.
Gates and Parking info: http://www.circuitcat.com/en/carreras/f1_test/mas_info.php?c=25&ed=152
(I’m guessing a blank box means closed, and a red X means open, I would have used a green tick/check myself, but ok)
Also found this info about ticket collection at the track:
In the Circuit de Catalunya:
The collection times are:
From Monday to Thursday from 9 a.m. to 2 p.m. and from 3 to 6 p.m., or Friday from 9 a.m. to 2 p.m. at the Public and members information point, located behind the main gallery (access by gate 3).
The same day at the box office of the venue, except for Conducción en GT, Extreme Weekends and Bicircuit.
We remind you that you must show the card with which you have made the purchase and the ID card of the holder.
