Omgeee the reference to Taco Bell and Stanford!!! I’ve never been to the campus but that would make me hungry! It’s a poor substitute for the real thing (Alberto’s, Roberto’s, Lolita’s…etc.) but I still eat it once in a while 
To get back to OP topic, if you don’t think tennis is an option post grad, then use the sport as a means to get the best education for your major. Consider where you want to work and how the reputation of the school and major will affect that. You should love the school and environment too, so visiting is important. The overnights will give you good insight to team chemistry. My son had Harvard as an option but he found the atmosphere too, shall we say, social status oriented for his liking. He’s a casual sporty So Cal guy and he’s so not into that (the clubs and such).
