I come to this thread often to search for feedback on schools we are thinking of and find it very useful, so I thought it’s time I contributed a little!
My daughter is interested in engineering, and would like to stay in the Northeast with a cute town or city close enough to walk to. My husband and I are even more interested in schools that either give a lot of merit or are part of the tuition exchange program (I work at a participating college), so that’s where a lot of the schools of her list have come from. Most of my observations are pretty shallow 
and have more to do with the feel of the campus and area and less to do with the actual programs, since I know nothing about engineering and all of the programs sounded pretty cool to me.
Duquesne – Our first real college visit, so we had zero expectations. We all loved it. Loved the location. It’s in the middle of the city, but yet felt like a little quiet oasis - separated and quiet. Kind of the best of both worlds we thought. Pittsburgh seems like an awesome city. We visited this school when my daughter was interested in Physician Assistant programs and if she had remained interested in becoming a PA, she definitely would have considered applying here (they have a 5 year BS/Master’s program), although I did notice their equipment and classrooms were on the older side. The only negative for her was the religious aspect (which could be a positive to many). She’s not applying as they don’t seem to have much for engineering.
University of Pittsburgh - Pitt was a little more urban than we had pictured in our heads, with very busy streets running throughout a sort of widespread campus. A million large tours were taking place at the same time. The dorms we visited (the Towers?) seemed claustrophobic– not the rooms so much as the hallways. My daughter found it to all be a bit overwhelming. Probably didn’t help that we just came from the polar opposite type of campus (Duquesne). On the plus side – the architecture of the buildings are beautiful, they seem to have a million cool classes and majors, awesome football games to go to, and all of the students we talked to love it there. It’s in a great part of the city – seemed to be much more to see and do immediately surrounding the campus than the area around Duquesne. She applied as she thinks the positives were definitely worth another visit.
Muhlenburg – Pretty campus, nice old architecture, nice rec center and cafeteria. They seemed to have a great theater program. The negatives for us - it came across as too small of a school and there is no town close center close enough to walk to, as far as we could tell. We asked the tour guide if people ever go into town and she said sometimes they take the bus to WalMart or the supermarket. It’s just not what she’s looking for. She’s not applying.
Lafayette – Very pretty, impressive campus. It’s a pretty small school, numbers-wise, but seems larger when you are on campus. The town of Easton seems nice to me – full of small restaurants and shops, but I think it is a little bit of a hike. I got the impression that our guide rarely went into town, well because he said that. The big selling point for my daughter - they have a dog that students can “check-out” for 30 minutes at a time, or something like that. She may be applying, but it may be a bit too small for her.
University of Delaware – My daughter loved the feel of this school. It’s a traditional campus with a cute main street that runs through the middle of it. The students walking around seemed very casual and down to earth – lots of sweats and jeans. It’s one of the largest schools we visited, but didn’t feel overwhelming. They have a large stadium and I think the football games are popular to go to, but it wasn’t an over-riding theme. Lots of majors to choose from, large study-abroad program. This was one of her favorites - she’s applying.
Princeton – Gorgeous campus, slightly dark and wood-sy. Idyllic college-town. Lots of name-dropping during the tour, as far as instructors and guest speakers, etc. Really cool traditions like the eating clubs. My daughter loved it. She’ll apply, knowing the odds are extremely slim.
Worcester Polytechnic Institute – Very pretty compact campus with mostly older architecture. Dorm rooms we saw were dated but huge! Natural triples and quads seem to be common. They have 7-week quarters instead of semesters, and a big emphasis on large team projects, starting right from freshman year, and on study abroad. All of which were very appealing to my daughter. The neighborhood directly surrounding the school seemed fine – a little boring, a little worn down, but nice enough. One hour train ride into Boston. This was a favorite. She applied.
Northeastern – Modern, urban campus. It appeared to us to be more of an enclosed/traditional campus than Pittsburgh, with most of the campus together on one side of the street. Dorms seemed nice, the co-ops are a huge selling point, as is the city of Boston. Though Northeastern is also very urban, this campus was less overwhelming and more appealing to her then Pitt. That may be because Pitt was one of the first she saw, and Northeastern was one of the last. This is a favorite. She applied.
We also visited RIT, University of Rochester, and Harvard. All of which she liked a lot, but I have already carried on too much here :). She’s basically pretty easy to please. She most likely won’t be applying to U of R since it’s not on the Tuition Exchange list and even with maximum merit would probably be more than we’d like to pay.
