Paul2 - I think it's the sign of a good coach to say "well if you want to do it that's fine, but I don't think this is right for you".
I was gutted not to be able to do Dundee a couple of years ago, my coach took some other skaters. When they got back she said she didn't think I'd have got that much out of it, as I'd have struggled with the edge work (which they did a lot of!)
I agree that if you do struggle, ESPECIALLY with footwork or basic skills, it's probably better to spend money on more lessons at home, rather than a crash course. For someone who picks things up quickly, the chance to have a few intensive days and try other things is probabyl much more beneficial than for the strugglers (I include myself as a struggler!)
