I might have to try that photo scavenger hunt! I'm going to a REALLY small convention this month, so we might need something to do during the down time.
Usually my friends and I will get some pop and snacks at the Con Suit, we also go to random panels, people watch, sit and talk, go to the dealers room/artist alley, or we some times bring a deck of cards and play a few games!
Next Convention: Anime Detour
Scarlet Witch- Avengers: Age of Ultron
Laurel Lance (Black Canary)- Arrow
