I do quite a bit of work on Cultural Tourism at the governmental level (as well as on projects). I think the idea of a space with access to a lot of cultural products would be appealing although you might have to wrestle with the cruise organizers. Some cruise operators, as well as ferry operators, expect some income if they include attractions in their itinerary. There are obviously ways around this, and other ways of putting pressure on them.

The big buzz words in this field are "Sense of Place" - give the tourists a real Juneau-specific experience, and this can include presentations of music, poetry, etc. I think one problem with the jamming idea is, will tourists have thought to bring their instruments? Might need to be song-based.

If you want anything in details, feel free to PM me.
