Business Education at Columbia vs Wharton--ED App

Thanks so much to both of you for your in depth replies! I really appreciate the time you have taken to help a complete stranger. I am certainly leaning much closer to UPenn now.
I have a couple, if you have some time to answer them.

  1. Is it difficult to double major in CAS if you go to Wharton
  2. What benefits exist from going to Wharton as opposed to CAS for an econ major?
  3. Does Wharton have a party-hard culture or is it more intellectual? How does this culture compare to UPenn as a whole?
  4. How safe is Philly? Are there shopping malls/grocery stores/pharmacies I can go to off campus that are safe?
