They'll love it ZF.

I used to take my kids to story time at the local library. Our local primary school also had it, to coax people into going to the school of course but the kids loved it. Our library also has school holiday sessions which I've taken the kids to. They've had a snake handler, crafty stuff, drama etc over the years. The kids used to love it, it was a great way of killing a couple of hours and didn't cost a fortune.
