Once results come out if there are any that your child really wishes they could visit, I would call the school and see what your options are. Right now schools are scrambling but you know this is weighing on them too. My D visited all her serious contenders except one before she applied. When she got accepted to that one we quickly scheduled a trip. She never would have gone without visiting (it was the furthest from home and that worried her) and it’s where she now attends. Schools are aware that the visits are important so you know they are trying to figure something out.
