Can you take an overnight visit after an Early decision but before other App dates?

So if one were to get admitted SCEA to Yale (or any other school that doesn’t allow overnight visits unless a student is admitted) could you stay overnight BEFORE student visit days to make a decision before you shell out a crap ton of money on application fees and the related expenses? Has anyone else done this?

You can always schedule overnights outside of the college if you know any students there. None of my overnight college visits were done through the school. In fact I didn’t even know schools had stated policies about when students could or could not make overnight visits.
