When you accept a booking request, the renter is notified by email.
From that moment on, they have 96 hours to confirm or cancel their request.
Beyond this additional period, and without any answer from them, the renter's request will expire and you will be informed by email.
Please be aware that accepting requests never blocks your calendar and therefore does not prevent you from receiving other booking requests.
You can receive and accept several requests at once.
Whoever makes a payment first, will officially have booked your vehicle and this will automatically block your calendar.
