I would have said Dartmouth, but after this recent scandal, I have a hard time recommending that school honestly. There's no way to know if it's a "one time thing" frankly. But at the same time, you're at a different stage of your life, and finances matter more. I think UVA although more expensive also provides you some tangible benefits - diversity, nearby family support, location - you have to weigh the overall happiness of your family vs. finances vs. your dream school etc.
If you do pick Dartmouth, make sure to turn your phone and all other devices off during every exam...\
Also good lord man, 15 acceptances? Jeezus
