My son attended SPICE after school and during the summer from the summer before kindergarten until he turned 12 and grew out of it. I had no complaints. There are a lot of kids; if your child has been in a smaller day care there will be a transition but going to kindergarten is a transition anyway. The coordinator, Debbie Moon, is awesome.
At this moment, I don't remember the fees...
The one thing I would caution, and it doesn't directly have to do with SPICE, but when you fill out the parent information card for Butler, write "attends SPICE after school, please call parents if sick" in the margins, and highlight it if you have to. In six years, my son sustained two scrapes, got stabbed (accidentally) with a pencil, and ran a 104 fever twice and the school didn't call me as it was very near the end of the school day, and most kids go home, and he didn't complain. He went to SPICE. Of course, while playing his band-aid fell off - all three times - and once the wound got infected. Fortunately with the fevers, Debbie took one look at him and called me.
