If you decide to go the MSV route and maybe Brands Hatch, make sure you book a NO TRAILER day so people have to drive home what they bring which should make them a bit more careful and stop racing teams coming.
Tbh, I’ve done trackdays with race teams and they can be courteous and patient - with the added benefit of having the best seat in the house to see a GT car blitz past on a straight, flames flashing on downshifts - amazing to see.
I’ve also done trackdays where I have been harassed by road going 600bhp Supra’s with no patience.
I try to watch the first session (as often they will want to get out first - their impatience has a way of being obvious!) and mentally make a list of “cars I don’t want to be on track with”.
(and that’s before we get into the discussion of quick cars on the straight that are slower over a lap… )
I tend to take my ‘new’ cars to Bedford Autodrome on the GT circuit. This is reported to be the safest in the country. It’s pretty flat and because the circuit is wide and long (4 miles) your daughter will have space and time to learn.
I would also advise as others have mentioned hiring an instructor for the 20 min session which can be helpful.
I’d take a look at Motorsport Events. Ed runs his trackdays very well, does not tolerate misbehaviour so they tend to be very courteous. I wouldn’t be put off by the fact some are on airfields, they are still great fun. https://www.motorsport-events.com
I took my son out for a track day in an MX5 yesterday at Oulton Park, a “first” for both of us.
With being new to it, I was keen for us to have some tuition. So I ended up booking the day through Dave Moore, who is an MX5 club member and tutor - Dave is @Barmy1 on this forum.
I’ve had (on-road) driver training before, and I can confirm that Dave is an excellent trainer. We had a really enjoyable day out, using Dave’s car (an MX5 NB) and learning loads of good skills throughout the day. We’ll be taking my car for an outing at Oulton Park soon!
I did my first track day with Dave in his MX5 at Croft in May. It was a 65th birthday present and I had very enjoyable day. I agree that Dave is very good instructor and I also very much enjoyed siting in the passenger seat when Dave was in the driving seat.
Bearing in mind your locations, Snetterton might be a decent option. The 300 is a lovely circuit and if the sun is shining its a lovely day out. We usually stop over at the Premier inn the night before.
I like Curborough and think it’s an idea venue if the location works for you. It’s really a motorsport track so I don’t think they do ‘track days’ as such. The MX5 OC Club has traditionally run a taster day there each year - so one of those would be ideal. Even better would be attending the MUK approved AHASS Drivers’ School days they run. These include instruction on the correct / school-preferred lines and then feedback on performance etc. The day I did we did so many runs I was almost glad to finish! (So it’s very good value).
