Hi C.. I have been doing Music Together for over 5 years - I'm on my second time around some of the song collections. I have taken classes at both of the studios off Snelling, and am now in the classes at Arden Hills. I find it's definitely worth the drive - the intergenerational classes are a lot of fun and the "grandfriends" say they look forward to it all week.
For your first class, though, and depending on the ages and temperaments of your children, it might be easier to start out in a studio where there are fewer distractions and places to run off and hide.
We've never had a bad teacher, but really enjoy Linda's classes.
Definitely try one of the demo classes if you haven't already. The next session won't begin until summer and it's a shorter session. You may be able to join in some of the classes underway but I don't know if there's any reduction in the fees.
