I have a recruiting/visit weekend coming up for one of my prospective PhD programs (to which I've already been admitted). Travel is covered, and my hotel is paid for. Food is provided the entire weekend. I had intended to bring my girlfriend. She is my SO of 6 years; we live together and moving somewhere for school would be a big decision on both of our parts and she really should be visiting the city/school before I accept anything.
She of course doesn't need specific details about every aspect of the program, as I will no doubt receive, or to meet faculty, and of course the university has no reason to pay for her weekend. My parents also were hinting that they wanted to come, but that's an even bigger stretch, it seems.
Am I overthinking this? Or is it really not appropriate to be bringing a +1 to a recruiting weekend. I can always bring my family members there soon after to show them around.
