Your H and my H must be cut from the same cloth or something. Because my husband behaves the same way on college tours.
We learned this all the hard way with D24. I should have known he would be like that but my brain must have been in la la land or something.
Because during D24’s 11th grade, we went on road trips to:
- Albuquerque to visit UNM
- Las Cruces to visit NMSU
- TX to visit Austin College (near Dallas) and Southwestern University (near Austin)
And OH. MY. GOSH. was he opinionated. It almost became comical. Stuff like:
- during the info sessions before each tour, he’d ask the admissions person a gazillion questions. So many questions that you could tell that everybody in the room wanted my spouse to shut up. WE, his own family, wanted him to shut up. One time, I suggested that he maybe stay behind and one of the admissions officers could answer any additional questions he might have.

- right after each tour was done, he would say, "Yup, I think this is The One. You should go here because reasons. Babble babble babble for 10 minutes about reasons.
- Then after what felt like 10 min of him essentially talking to himself, he’d ask THE CHILD what SHE thought of the school. At this point, she’d be so sick of listening to him that she’d say something very bland/middle of the road or she’d say, “Eh, I don’t know,” which would set my DH off to the races.

Didn’t learn our lesson about that until we’d done both of the NM college tours…and D24 pulled me aside and asked for help in getting Dad to shut up about his opinions.
So by the time we visited the TX colleges, he was still intense but not quite as much. And he’d at least kept his mouth shut about his opinions until D24 had voiced her own ideas.
…this is all why I was the one who took D26 to tour Univ of Arizona and why DH did not join us.
DH is going w/D26 & I in a couple of weeks when we tour Embry Riddle University in Prescott, AZ. DH has already promised to keep the intensity to a low roar and to not voice any of his opinions until after D26 has had some time to think about it. 
One suggestion I’ve used from I can’t remember where I got this suggestion is to ask The Child (when you’re in the car on the way back from the tour) to name 3 things they liked about the college and 3 things they didn’t like. Jot those down somewhere (because your kid will forget what those 3 things were later on). Ask The Child to explain why they picked each of the 3 things. And you, the parent, doesn’t say much. You mostly just listen. But it’s ok to offer up some of your own thoughts to maybe expand a little bit on what The Child said.
And so far, this technique has worked out really well.
For example, when we were on our way home from the UNM tour, D24’s 3 likes were:
- it’s less expensive than Univ of Arizona
- it’s not quite as big as Univ of Arizona
- 1 hr plane ride from home or a ~6.5 hr drive
UNM’s 3 dislikes:
- how dark it was in the areas outside of campus at night
- didn’t feel safe at night
- didn’t feel safe at night
NMSU she didn’t like because:
- dining hall food was terrible (we all agreed on that)
- campus felt very spread out
- didn’t feel like there was enough to do on weekends
Centre College likes:
- beautiful campus
- small class sizes, everybody seemed to know everybody else, felt like a real community
- town the school is in was “adorable” and we found “decent Mexican food walking distance from campus”
- honorable mention: campus & town VERY VERY safe. Also everyone VERY VERY friendly
- 2nd honorable mention: VERY affordable, AWESOME arts program, liked how you can take glass blowing for your art GE requirement.
Centre College dislikes:
- a little too far away from home
- hard to get a ride to the airport
- felt like it might be a little too cold for her (we went in Feb).
Honestly, we all loved Centre College. I’m still sad that she didn’t pick that school. And I’m sad that D26 won’t be applying (since she wants to major in cybersecurity). Centre also has some really excellent 1st Gen programs and great scholarships for a wide range of students.
ASU (which is in our metro area) was a big fat no because “it’s too big, it’s too close to home, and Daddy wants me to live at home and I don’t want to live at home for college…I mean I love you guys but I don’t want to live with you & Daddy during college. And ASU feels like a big corporate office complex.” 
We’ll get through it! My DH’s college experience was way different than mine. When he went on college tours when he was younger, it was all on his own. His parents never took him and it would never have occurred to them to do so. So I think some of his intensity is that he’s new to all of this and he’s also excited about it all. 
It’s a hard balance sometimes!
Sorry for rambling.
