The sand is very firm up near the front. The cars are mainly a bit too far out - sort of closeish downwind (thats probably why they are still there - they do take a good few tides to actually sink).
There is plenty of room but up at the Eastern end there are lots of sneaky channels which look insignificant from the air but would really ruin your day so don't be a hero "going for the numbers type". There is soooooo much beach if ,as I think they'll be on Wed, the tides are right.
Would suggest maybe a precautionary flypast but you'll probably see other folks wheel marks.
Enjoy
ps don't know where the refreshments are but the fish and chips from up the western end are v good.
