Managed to choose most of the events I'm doing over others, but I'm still between the Hacking in Fiction, Games, & the Media and the Comedy Cabaret. Does anyone have experience with either of these in the past? What were your thoughts?

I only have experience with the Comedy Cabaret. My crew enjoys attending the musical performances already. But the Comedy Cabaret is a string of short performances from most of the musical artists. It's a great way to sample all those artists, and, since it has moved to Thursday, it gives you time to buy tickets for any performer you especially like (assuming they aren't sold out, or you want to take a chance they will let you in with generic tickets). It's one of the few must attend events for us each year. Highly recommended.
