There’s a big difference between UCSC and Stanford, in that UCSC students rarely live on campus for more than 1-2 years. After that they are generally living down in the town, and get the bus to campus for lectures. Whereas Stanford students typically live on campus all four years. Many public colleges are more similar to UCSC than Stanford, with limited on campus accommodation. And then options for eating out at lunch are very different to eating out at dinner time. And the primary consideration with regard to separation may be how far away from campus you are likely to be living.
