Right i've spoken to some gyms and i've managed to book a hall for the 2nd July which is a Saturday and will be between 12 and 2pm, i managed to get the guy to take the price down as much as possible and for 2 hours it will be £32 for the entire hall which is pretty big. Now if we don't have the numbers then we can have half the hall for around £20. If you are unsure if you can make it please post anyway as i need to work out an estimate of how many will be likely to be attending.
The address is: The Manor Sport and Recreation Centre, Kingsley Avenue, Mansfield Woodhouse, Mansfield, Nottinghamshire NG19 8JY.
Thanks, Chris.
Edit: heres a picture of a rough view of the size of the hall:
