We've had a great experience with Apollo for PK3 and PK4 at Garrison. it's not uber-fancy, but our kid likes the teachers, is with the majority of their classmates, has fun, and sometimes even complains when we pick them up too early, lol. A majority of kids at Garrison do some form of the aftercare.
It's about $430 per month and runs from 3:15 til 6pm, unless your child qualifies for free tuition or a reduced rate. Fingers crossed the lottery works out for you; Garrison is a wonderful school community.
