That’s fantastic she is so invested.
I think it’s fine to visit far away safeties after she’s been accepted but I would suggest she compromise on the small class size though and add at least one in-state public option that is affordable that has her major if there is one. It’s not going to hurt to apply and things change. She might decide to stay close up home. And in-state options are generally easier to visit. After COVID you just never know what’s going to happen. Good to have one option close to home in case the world goes to heck again.
Up until two weeks after high school started last year my D22 was sure she wanted to go to school overseas and had even rearranged her senior year class schedule to make sure she could meet certain requirements but she kept looking and thinking about things and ultimately decided she did want to stay in the US. Until Deptember or so she was seriously considering some schools in the Midwest ( we are in NC) and I was trying arrange a road trip on her fall break so we could visit them but then we visited a small in-state LAC and she fell in love with it. She ended up at that school, but also applied to two in-state public schools (one big) as safeties and two other LACs OOS that were targets (but not the Midwest ones). No reaches. She got in all of them.
