Stuff Only Potterheads Will Get

Chamber of Secrets

I wonder, if the students didn't evacuate during the Battle of Hogwarts, would they have gone to the Chamber of Secrets? 

Think about it, only two people can get inside Harry and Voldemort, (who probably isn't going to come waltzing into the school) it's surrounded by stone so it wouldn't collapse, and it's virtually impossible to find.

I kinda want to know what this would be like.
