My daughter went to stagecoach for a couple of terms when she was 4, but we didn't get on with it very well. I'm sure some of the franchises are great, but our particular one had a very unfriendly principal, who scared me let alone the children. The session was 1.5 hours on a saturday afternoon, and my dd found this too long, and also the whole thing was just too serious for what we were looking for.
My dd had a report sent home at the end of one term, although my dd had already discussed with me that she really didn't want to go anymore, it was too hard, she found it too much to remember, and too long (for a 4 yr old) Anyway, the principal had written in her report that my dd giggled too much, found it a bit of a laugh and didn't appreciate the 'opportunity to perform' like she should.
Personally I was very cross that a) they hadn't mentioned anything to me prior so I could try and sort it out, and b) if you can't have a laugh and a giggle at the ripe old age of 4 then what hope is there for the future.
She now attends the Helen o Grady drama school, which is only 1 hour (plenty), on a school night, has great fun, some weeks they take in props to dress up etc, and the teachers are brilliant, the bonus aswell is that it's half the price, and they don't have to buy uniform, whilst at Stagecoach they did. I had to buy some jazz shoes at about £15 from the principal that I really couldn't afford, but felt far too embarrassed in front of the other parents to say so.
Sorry for rambling, just to sum up, in my opinion, Helen o Grady is much, much more relaxed and fun, and my dd has come on in leaps and bounds there.
But I also appreciate everyone has different experiences and different needs and wants, so I'm not saying other stagecoach venues aren't good, just my experience of our local one.
