Me: 

No!  Even if they go to the front door, they won't be able to see 
them.  Remember when Harry goes to the door just before he reads 
Dumbledore's note?  No house!  The charm doesn't just make it 
impossible for those who don't know about it to find it...even if 
they had lived there all their lives, they wouldn't be able to see 
it unless the secret keeper told them the location.
