Trying to make such a big life decision without in person visits is tough. Can you describe your D–likes and dislikes, what she would enjoy doing at college just for fun? Is she a social justice warrior, taking food to the homeless on the streets, or an introvert who will stay in her dorm room 24/7 ? Would she find a pick up game of Ultimate Frisbee on a sunny afternoon, or find local museums to tour in her free time? Is a social life important, Greek life, intramural team sports, the Ga Tech football games are a big deal on campus, lots of school spirit, does any of that interest your D ?
In and around Ga Tech, you can hang out and get the best greasy food at The Varsity, attend a play at Shakespeare’s Tavern, eat international cuisine, attend Dragon Con over Labor Day weekend, attend music concerts, and take advantage of one of the best Recreation Centers on a college campus (home of the 1996 Olympics for swimming).
You can escape to smaller towns in metro Atlanta via Marta trains, or drive to the Georgia mountains and get in some hiking. Stone Mountain Park is a huge draw for the area, and even now during the shelter in place, we are allowed to go there and hike the trails, some of them right by the lake. You can hike up Stone Mountain (the largest outcropping of Granite in the world) and when there is not a pandemic, there are restaurants, museum, attractions, laser shows at night in the summer. Six Flags over Georgia is a short drive from campus.
Double check on deadlines, I believe many schools are extending their decision deadlines. Admissions Offices should be able to connect your D with students in her major, to get more feel for daily life on each campus.
Also go to the colleges and universities Forum here on CC, and read posts about the schools you want to know more about.
I would say Ga Tech is your top bet on paper, and you should investigate MIT to see if the fit of that campus culture would have anything to offer your D above Ga Tech.
