Yes, it's worth your time to take collegiate trips. Looking at a college's website and reading pamphlets can only provide you with limited information. When you visit a college, you get to absorb the atmosphere on campus and hear firsthand impressions from the students themselves. Plus, when you tour a campus, it allows you to imagine yourself as a student there. An in-person campus tour and your research at home should combine to give you a clear impression of the college.
