This is great and if you go local as subs…for example, Elon is - while not in the sticks, it’s in the sticks as far as day to day - just a tiny strip off campus. If you know you hate that, then some on your list can come off. So local for comparison sake is ok.
I wouldn’t change the email addresses I gave - although you can fill out another info request and use the new. That way you get it both. Then you can just unsubscribe from the old. I like the college email - just so you know everything college is in one place.
Not all require demonstrated interest - so you don’t have to open all. And you don’t have to go crazy. Open emails is fine. Play a video, walk away is fine. It can be weekly, not every day. You can jump on an online admission session for those who track. I don’t think you need to go crazy - like some try to do 80 things - a few things that show you’re paying attention.
Maybe no Charleston - it’s smack in the party zone. The Fellows is definitely more studious - and I was just recommending for that. It’s not many kids and they are the creme de la creme. But the school is smack in the tourist zone. It’s a condensed campus, very historical.
PS - as for legacy, maybe, just maybe, it can break a tie. But I would apply to Harvard if I wanted to go to Harvard and I wouldn’t if I didn’t want to. Like wondering about - where you come from, does it give an edge? I wouldn’t worry - because you won’t know. Apply to the school if it’s right for you and don’t apply if it’s not. There’s even public LACs - St. Mary’s of Md is small (and likely affordable), SUNY Geneseo, in VA you have Christopher Newport and U of Mary Washington, in NC UNC Asheville, College of Charleston is one although 9k kids. In the end, you will be somewhere four years, day after day - so applying to a school mom wants you to apply to, if it’s not right for you, makes little sense.
So UNCW and UNC are fantastic but if they’re too big, there is smaller. Same with Harvard. Brandeis, as an example, would be in that area but smaller.
Go visit some larger campuses locally - see if you like them.
Best of luck to you.
