Unfortunately, as in the “note” [on official visit page] official visits are a thing of the past. Because of the accelerated recruiting process within the women’s game (not sure of the men’s time line to this), it is more likely these days that you’ll be spending your vacations, spring breaks, etc… researching and taking trips to the colleges/universities that you’re interested in!
You are allowed to take as many unofficial visits as you wish, because this is basically at your own expense to do so. You’re allowed to do everything that you would do on an official visit, however, there will be small fees involved. For instance, if you’re wanting to spend the night with a player/s in their dorms/housing then there will be a fee for this, if you go to eat with the players, coaches, etc… this will also be at your own expense.
