Hi Alice, sorry I didnt see this post until now. Im waiting to see if my sister can help. She has the little ones with her, so might have to work something else out there. And also a friends wife volunteered, but now unsure about child care as one of them is poorly.
Worst case scenario, I will come along, peel some spuds, then scoot off in the mini bus.
Another friend Ali, is able to give some time between 9 and 12 if that helps with anything.
