In some ways the Willie Clancy and Whitby couldn't be further apart.
Whitby is an hour and a half of something, then wander off and do something else. Dip in and out as you please. Loads of beginners or near beginners and chances to try something new.

The Summerschool is for the enthusiast - you commit to spending every morning for a week doing the same thing with the same teacher. I think the music classes are graded by audition first. Nothing programmed for the afternoon (sessions or singing in all the pubs to listen to). The evening concerts are very single minded too. You need to be keen to go to a whole concert of (say) flutes.

We've been twice, for the Set Dancing. Enjoyed it very much (since we were keen on Set Dancing). And it's a beautiful place - enjoyed a glimpse of dolphins both times. But driving across Wales, a long ferry crossing, then across Ireland means we probably won't go again.
