...has two rooms that I know of that are sort of bigger on the inside.

The nurse's office has one entrance/exit, and its own tiny hallway leading to that entrance. The actual office part is big, and there are two doors. The first is the entrance, the second leads to another room with another door, which leads to the bathroom or another door that leads back into the office with the entrance/exit.

The second is the TV Production room. You enter, there's sort of a lobby, and then a classroom, but if you turn it leads to a hallway and the studio, which both go to the classroom or control room, and another door takes you to an off-limits hallway. Which leads into the library or the courtyard oor an on-limits hallway leadinh back to the "lobby".

Both of these rooms have normal-looking doors. Also, the TV room's control room is smaller on the inside, making it hard to fit half a class of (mostly)strangely athletic and popular computer nerds in there. crying said athletic popular nerds give me a lot of crap, BUT ANYWAY....
