How much to the Claremont colleges compare to a single university?

<p>Hi there,
I know similar questions have been asked before, but how do you all feel about this?
It seems cross registration works seamlessly among the colleges, so I would like to focus more on social aspects of the 5Cs. How often do the colleges interact?
Are friends made mostly through class or parties?- How inviting are other colleges in parties and social events.
Are career resources/networking only specific to each college.
Sorry if this seems overwhelming, but to sum up, does it feel as though you are having a larger college experience with comfort of your own small one?
Thank you!
P.s, how do you all feel about Pitzer students?</p>
