Leaving camping during the 2026 24h

Hello! I will be attending my first 24h (solo) this year. I am lucky enough to have relatives living about 40 minutes away by car. My plan was to show up early in the week either monday or Tuesday to secure a camping spot. My question is if it is possible to leave the camping with my car to sleep, recharge batteries etc at my relatives house untill race start on saturday whereafter i plan to stay at the ring and camp for the full 24h race. I am quite familiar with the area but have never been there during the 24h weekend. Thanks in advance!
