No such problems on Bleu Sud. They had been round with the spray cans marking pitches but no-one really bothered keeping to them, it was sort of self policed, didn't see anyone taking the piss regarding pitch size and as a result the security guys were quite relaxed.
We were in and out all w'end with the van too without being scanned, just a quick glance and a smile! Worked out quite well I thought although there were some very rough, uneven and boggy spots that were marked as pitches.
