<p>I’m having a hard time figuring out why it should be much more than one day. On the back end the school with have activities planned for you child after they check in and the schools I know about (a limited number for sure) have stuff that first day for families and that is about it … and I do not think you want to be hanging around after the school has planned on you leaving. On the front end there is no need to get there extra early other than if travel gets you the night before … being on campus before all the other students could be counter productive.</p>
