HI. I'm bringing a group of 12-13 college students to Jerusalem this summer and I was thinking of planning a scavenger hunt as part of the orientation to help the students simultaneously get to know each other and begin to explore the city. I see that Jerusalem Scavenger Hunts (http://jerusalemscavengerhunts.com/) already exists. I'm trying to decide whether to plan my own hunt, tailored to what the students will be studying, (I'm not that familiar with Jerusalem but I could research places to go) or pay to work with this outfit. Has anyone done one of these hunts? Would they be good for college students? And which tour is better -- The Old City (which we'll be touring with a guide) or Nachlaot?
