I booked this for the children who attended our Summer Holiday Club. It was absolutely fantastic for all the children with an age range of 3 - 11 on the day. The children had a great time and I would book this again with a slight twist. I wish I had explained we had an autistic child attending on the day. He wanted to feel the different coloured sands one at a time but I was asked to remove him in case he mixed the sands up. If I had known he wasn't able to participate I would have bought some coloured sands for him to use as he wished.
