Once again it's proven that there's no perfect way to write an initial post. If you include all the info, then it's too much info and people lose track. If you dole out the important info as you go along, it sounds defensive and it's hard to make people believe you.

Make her get a flu shot. That is the worst. Kid with the flu and you are hours away. Stinks.
Make a plan for when her body doesn't work with the shot and she still gets the flu. Or when the flu on campus is annoying enough to not be the one a manufacturer picked out of a hat 6 months ago.
I never got the flu in college, but when I was 30 jinkies, thought I was literally going to die one night...living all alone, friends all married and most with kids and having their own lives... My mom called one friend (who almost never "got sick" because she was on more immunosuppressive drugs than a liver transplant patient takes (which we know because she has since had a liver transplant and takes far less of everything)) and asked her to go shopping for me and drop off the bag at my door.
So make a plan anyway! Get friend's phone numbers.
Not for move-in day, of course -- that requires a car trip with boxes, bedspreads, and more.
Not when you're far away. Move-in for me involved me packing up what I wanted to have there and shipping it up within a certain time period before orientation. I took the rest with me on the plane. No drives for me!
I grew up in the Bay Area in CA. My mom wouldn't let me go to NYU because it was too far away (the city was fine for her, as she grew up in NY and visited NYC routinely with family as a girl, and later alone as a teen). So I got into college in WA (I *had to* leave CA b/c I was literally allergic to everything tested for and don't like drugging myself AND the drugs don't work anyway, well except for Seldane but that had the pesky problem of killing people). And then...stepdad filed for divorce, and mom's childhood sweetheart swooped in to propose, and to move her to Miami, FL.
So off I went to Washington at 17, with mom moving a week later to Florida. I was a shy, nervous person and we would NEVER have thought I would survive with such a distance between me and my most beloved mom, but it worked out. Pre-cellphones, she actually got an 800# so that I could call whenever, and for however long I wanted to, and I wouldn't get the bill.
And some children are raised to take into consideration what their parents have to say.
And some younger humans simply WANT to take into consideration what older humans have to say.
We're talking about school breaks plus two weekends each semester. You really think that's helecoptor-ish or holding the student back? You really think that's not trusting a teen?
It's definitely more than I saw my mom. It's more than my friend, who grew up in the town where our college is, saw her family. She was cross-town, maybe 15 minutes, away. She did just get so involved in everything that she didn't have the time. She also was still dating her HS boyfriend at the start of college, so he took up some of her time...but once they broke up it still didn't change.
Will it hold her back? Who knows?
Man, I remember some "college experiences" that I would like to have been held back from... If other options had existed (other than feeling like a loser in my dorm room ALL weekend long) I might have taken them. The best studying-for-a-final I ever did was with old family friends who had moved to Oregon...I drove down there and stayed with them for several days, and got the BEST studying done. Would have been even better if I could have been at *home* (but my home was gone a week after I started college).
When the time comes for DS, I assume he'll go where he thinks its best for him. My brother and sis in law are pushing for their alma mater, Duke.

Of course, I've already told DS (and will continue to tell him) that one of my favorite places in the WORLD is merely hours away from Durham, so assuming he remains our "only", we might just have to move out to Asheville.

But then WE would be so busy we'd never have time for him to visit!
Sounds like there's good and bad with both colleges. Make a pros/cons list, definitely being sure to include *feelings* and projected feelings on the list. I could "see" myself at Tulane, NYU to a certain extent (though in reality I bet the city would have chewed me up and spat me out inside a month), and where I went. After narrowing it down more and more and more, I chose the one in WA. My mom never went to a 4 year college, and had NO idea how to help me at all, so she really couldn't give input.
But hey, if she makes the wrong choice, she can always transfer!
