Look into all scenarios, especially off-campus residence situations. Often, institutions that have graduate programs attract stronger faculty than those that do not. Of course this is by no means a rule etched in stone - just something to look out for. Students can be benefitted from studying with Professors who are active in research in their area. Such research opportunities are often better accommodated by schools offering graduate degrees.
Family traditions can be hard to break.
Of course you may not need to break one. But, if the school simply isn't what you need, then you have some lobbying to do. It can help to bring in high-school counselors in on this discussion. One of most telling exercises can be to meet graduates and current students of this prospective institution. By all means, make a trip to visit the school.
