Dear Sean:
Go! You'll truly enjoy the experience of a week-long imersion in traditional music.
I've been to Swannanowa for contemporary folk music week, and to Augusta during Irish week (I took the week-long string ensemble workshop with Cathy Barton, Dave Para, Larkin Byant, Becky Blakley, et. al.) However, my favorite place is Pinewoods (I've been 3 times) during Folk Music Week. At Pinewoods there seem to me to be a much closer overall "community" relation with the other student/campers and with the guest artists/instructors.
Please be forewarned. After a full week of song, dance, learning, and sharing, it is most difficult to get back into the pace of the "real world".
