As is a "Fest," such as these two:
Oz Fest 3 (Brisbane, May 26-28, 2006)
Meat & Malbec Fest 2.0 (Buenos Aires, this weekend)
A "run" generally involves groups taking the same flights, usually on a bargain fare, with other activities secondary to that purpose.
Other terms, like "dinner, are generally self-explanatory.
Try it, you'll like it!
