Any one free the afternoon of 23rd April to help me with a school maze event

I am doing another maze event at Bishop Henderson on 23rd April (Galmington, Taunton) - this time for a sports fair in the afternoon (so setup from 2:15pm and finish by around 4:30pm).

Is anyone free to help out? I would like to have a few people around so we can be a bit more engaged with the kids (and their parents) as well as doing all the si admin!
