Ok, i've contacted the Alan Higgs centre in Coventry. They said that they have free slots:
Thursday 8:30 - 10
Friday 8-10
Although I can't make Fridays.
I'll probably make my way over there at some point this week to have a look at it and let them have a look at me on stilts.
I was also pointed at Woodlands School and have e-mailed them about using the facilities there.
