A number of years ago a daughter had five acceptances to five universities that were all affordable. One she (or we?) quickly eliminated based on academics. This left four that were all affordable, all in attractive and relatively safe locations, and all academically appropriate.
Past this point, it was entirely her decision. As parents we could give opinions, but any choice that she made was fine with us.
We did arrange to visit all four, went with her, and paid for the trip. One was a bit more difficult to get to so she cut the list to three. She sat in on a class and talked to a professor at all three.
How did she decide between the last three? It was actually tough for her (and would have been tough for me if I had been expected to decide). You make a list of pluses and minuses. You visit and see how it feels. When you have already been accepted with an affordable offer, a visit feels very real – the student knows that they really can be here as a student in September if they want to do it. You consider cost, academics, travel difficulty, the location, and whatever else comes to mind.
After considering all of the relative advantages of all of the choices, sometimes the student just needs to forget about it for a couple of days, and then do whatever feels right.
Having the student make the decision makes sense in multiple ways, including the fact that they are the person who will need to be living there and showing up at class and doing the homework. Also, going away to university is a major path in the direction of growing up and becoming an adult, and letting the student make the decision is a big step on that path.
And as @tsbna44 said above, sometimes there may be no bad choice. Sometimes you have multiple very good choices, and you just need to pick one.
