Leaving race car and trailer at the circuit

[MR2_SC]

I'm planning to start racing this year and just trying to figure out the practicality of a race weekend.

Assuming I want to test on a Friday and then race Saturday and Sunday. If I'm not camping on site and want to stay locally is it allowed/advisable/safe to leave the race car and trailer in the paddock over night or should I take it all to the hotel every night and seek out hotels with secure parking?

I would assume that entry/exit to the circuit is tightly controlled so it's relatively safe?

Do I need to buy some security like a wheel clamp for the trailer and chain to attach car to trailer or is it generally a safe environment to leave it overnight?

Thanks in advance for your advice.

Thanks all.

I'll aim to leave at the circuit but add some security to be safe.
