YMCA classes are way better than Jumping Beans (IMO anyway)!! Lots more activities to do, longer sessions and they teach how to land properly after jumping off things and how to do forward rolls correctly etc. We have done a few terms with YMCA and its half the price of Jumping Beans! I found Jumping Beans didn't push Laurens boundaries enough.
I definately recommend you give the Y a try!
No offence intended to anyone that loves Jumping Beans though
