Temple itself...like the campus is pretty safe. there are security cameras and/or people on literally every corner. the most unsafe part would be the walk from the train station to campus just because there's section 8 housing in between the two...but with that being said, its only three blocks to walk and if you're with a group of people its not a problem. i walked those three blocks by myself twice everyday this summer and never had a problem.
cheesesteaks-i personally think pats & genos are overrated. if you want the "philly experience" definitely go, but i prefer steaks on south (about 4th & south streets)
food in general-philly food carts are DELICIOUS! they're pretty cheap too. its a good bit of philly culture as well
colleges-philly has a ton of colleges in like a 20 block radius (penn, drexel, temple, university of the sciences, and some others that im forgetting). i know some teams go on college campus visits while in cities, so you may want to consider doing that
hotels-here is a url listing all 237 hotels in the city
