You want kindling? Well, my main instrument is upright bass! 
And I didn’t mean to dump excessively on Olivet. I REALLY appreciate it for hosting this music camp. I guess a part of my impression was colored by my expectations, experiences, and biases.
I attended UofI as did 2 of my kids. The 3d went to Illinois State. The all-in cost at Olivet was considerably higher than the costs at my state schools, so I tried to assess what that extra $ would get you. Sure, it is smaller, so I imagine there is greater access to faculty and other factors that would come with small size (if you consider those plusses). And for all I know, their faculty are world leaders in their fields (tho I doubt that.) I imagine they are very good teachers, interested in interacting with the students.
My impression of the dorms is undoubtedly colored by my 3-4 post-dorm decades living in far nicer surroundings. And I guess I’ve seen enough media articles about lavish dorm “suites” and such, that these little, somewhat worn and dated living cubes made an impression on me. The comment re: AC in Mich makes sense.
There may be 3 buildings that they say host classrooms, but believe me that there is one single 4 story building that hosts the vast majority of their classes. Nothing about that building is new or lavish. I admit that as a summer camper, I am familiar only with the dorms, the main instructional building, and the dining hall. I freely admit the food is GREAT!
And I have ZERO experience with the student union, the rec facilities, etc. Those might be top notch for all I know.
What is the demographic these colleges serve. Often I will be driving somewhere, and I’ll notice signs for a nearby college or university that I’ve never heard of before. I often wonder what would attract prospective students to attend such colleges - unless there were a specific major that school excelled in. I question whether these small schools would have fantastic reputations, extensive alumni networks, many seem to be in unattractive locations, etc. I guess the religious aspect is important to some people. But in most cases, to my jaded eye, a combination of local community colleges and state schools would generally be at least a comparable option, often at lower cost (at least as far as sticker price goes.)
Sorry I’m so ignorant about this - happy to have my ignorance dispelled.
