Hi Lizzie!
I read your question, thought of what I'd write, then realised that Whirly had written exactly what I was going to say!
There is absolutely nothing to be lost by having a couple of "trial lessons" with other schools before you make up your mind (but do make sure that the instructors are aware of your experience, and don't treat you as a normal trial lesson).
But once you've done this, I suspect it will come down to some very wise words which someone once told me: Toss a coin - and when the coin comes up with the wrong answer, you'll know what the right answer is.
Let us know how you get on!
