Open House v. Campus Tour

Hi I’m planning visits to a few colleges for the upcoming months and I’m wondering if someone would be able to explain the differences between an open house and a campus tour. I’m curious as to the pros/cons of each as well as a general breakdown of what each experience consists of.

An open house usually has a lot more activities that prospective students can participate in such as admissions presentations, sitting in on a class, campus tour, residence life tour, etc.

A campus tour is usually just as it say, a campus tour.
