Help me pick games to run

OK, so if you're a judge for 6 hours at KublaCon, you can get your full registration refunded. I'm cool with that! I was thinking that I could try to pick games you guys would like to play/would play anyway and then try to just get you guys in. Of course it could all backfire and culminate with Eric being raped on the table by Ham Man. But I thought I'd give it a shot.

I was thinking about some combination of the following:

Game of Thrones (3 hours)
Ticket to Ride (1-2 hours -- probably a barjillion games of that already)
Puerto Rico (hey-o!) (2 hours)
Space Hulk (2 players, 2 hours)
Risk: Godstorm (2-3 hours)
Pirate's Cove (2 hours)
HeroScape (4 players -- 2 hours)
Alhambra (2 hours)

Shit I dunno. Anyone?
