We just attended the admitted student thing last weekend - maybe the same weekend as you? It was a huge event. I’d have a hard time hanging my hat on the interactions with a few upper classmen who obviously don’t share her thoughts. I had two kids there; 1 stayed with his group and had a blast; the other ditched her group and did something else and had a blast because she realized that they weren’t a good social match. This is our second visit this year, and second overnight. Lots of different personalities each time. Best of luck in your decision.
