I rode Wiggle 6 at Catton Park and we were all in a Parc Ferm with no outside help allowed and no nipping back to the car for food, drink or spares. Everything had to dumped in the Parc Ferm before the race started.
I've done various other solo events and it's a bit more relaxed.
Bristol and Cheddar have a solo gazebo at the side of the track, at Mountain Mayhem Set2Rise and Hit the North it's possible to park right alongside the track and use the car park/camping area as your pit.

What happens at SITS ?

|Normal set up – no Parc ferme jazz

Big marquee for solo riders if you want to use it. Personally it'll be the tent again.

Can we park right alongside the course then if we get there early enough ?

Should be able to, there were plenty of solo riders that did last year. Probably heading over Thurs night.

OK, thanks. I like to leave my food and drink out easily accessible. I like to have my spare wheels and other valuables locked away, but not miles away in a distant car park
