Yes all good to park overnight. Get's really busy this time of year. If you arrive early morning or very late afternoon is the best time for getting a spot. Otherwise you would be very lucky to park anywhere near the turning circle. Most likely way back down the road in my experience. While I agree with NNW in that you could not pay the entry fee and get a reminder ticket on the windscreen, that could escalate to a substantial fine if you forget to pay. My suggestion would be to pay as you enter the park unless it's after hours (or you already have a pass).
