We arrived when travellers were expected and they had put up bollards at the entry, it is a huge car park, and we decided we would try. We got through, just, it was the bottom of our wing mirrors that almost caught the top of the concrete bollards, but another Brit joined us, saying, he wouldn't have on his own, but as he saw we had got in, he reckoned he could. A french motorhome tried three times and gave up... Hopefully you will go at a different time. Great huge space to park
