Should I or Should I Not? (Mall Scavenger Hunt Question)?

[~m~happy_giggles~m~]

So for the Mall Scavenger Hunt I was thinking of putting taking pictures of certain items or members doing certain things on the list. However, I don't have the facility to provide cameras for both the teams, so I was thinking they could do it on their cell phone. I don't want to look cheap so I even thought about giving them my other cell phone to use incase they didn't have one. What should I do? Should I go through with it or delete that portion of the scavenger hunt list?
