If that was my grass I’d have sunk a bollard in there over night as you slept.
Your only course of action is as follows:
Get someone in to turf the grass over, a very large bouquet of flowers, an even bigger box of chocolates.
And in terms of apologies I’d be thinking of something along the lines of a flotilla of biplanes trailing ‘sorry I’m such a dick’ signs from behind, followed by the red arrows dropping a thousand red rose and then you can go and park your van somewhere else and learn some respect.
Should just about cover it.
