Chelsea Flower Show

Hi

I have 2 tickets for Chelsea Flower Show (mid week, members day), was really looking forward to going with hubbie but work may now call me away for the week/abroad unexpectedly.

The tickets state non transferable so I'm guessing I can't swap them for Sat when I'm back.

If I give them to hubbie to take a friend does anyone know what checks take place at the gate to check they've not been passed on to another? I've only been on non members days before and they didnt ask for ID. I'd hate hubbie / friend to be turned away as they're not 'me'...
