There is a Bodhran Weekend Workshop going in June in Germany and I have heard yesterday, that there is still a couple of places free. Info in German language please find here http://www.nordkolleg.de/kalender/index.php?showdetails=138
There was a Low Whistle workshop planned for the same weekend but it had to be cancelled, not enough subscriptions. Unfortunately I did not know this earlier otherwise I would have let you know, a tin whistle one is planned some point in the future, I will let you know definitely then.
Have a nice coming weekend
