As far as I know, players cannot show recruits around unless on an official or unofficial visit.
Recruits can attend camps. Some programs do not run their camps on the field but use practice fields. Players can go on campus visits thru the school. There are online videos of player facilities.
It really doesnt matter what the player wants, but more what the coaches are looking for their program.
My son was recently told that if he wanted to make a visit he could schedule it through the school and then send a text when he was coming to the athletic facilities and they would leave and leave it unlocked for him to go through
