It's definitely going to be more difficult, Foxy can appear as early as 12 AM.
Foxy was very bypassable in the first game, just look at him again and again momentarily because if he gets looked at too less, he'll pop out, same with if you look at him too much.
Since you'll know when he's out when you look too much, you'll probably have the fast enough reflex to close the door.
