New Room Names

I've decided to give my bedrooms actual nice names to help keep them straight.  I've been thinking that one possible name for my house itself would be King's Castle, which is the name of the castle where Prince Charming lives.  I may come up for another name for the house itself, but I like the names suggested by that motif:

Master Bedroom becomes King's Bedroom
2nd Bedroom becomes Lab (shorter and more accurate than Computer Room)
3rd Bedroom becomes Queen's Bedroom
2nd Bathroom becomes Queen's Bath
4th Bedroom becomes Gym (more succinct than Exercise Room)

So, the new bedroom names are King's Bedroom, Lab, Queen's Bedroom, and Gym.

Alternate choices rejected

"Lord's Bedroom" doesn't sound any less stilted than "King's Bedroom."  Lord, which is the counterpart to Lady, has also gotten to mean something like God.

"Princess Bedroom" sounds demeaning.

"Mistress Bedroom" (the counterpart of Master) sounds even more demeaning.

And it's not so far out to use these names, considering we call our beds "King Size" and "Queen Size" and so on.  Actually the King's Bedroom now has a Queen sized bed, and that is the size that fits best into the room.  The Queen's Bedroom now has a twin sized bed, that will probably also stay the same.  These are not large rooms, in fact they are smaller than the bedrooms in most houses built after 1965, like my whole house.  But the comparative smallness helps keep the house efficient in many ways.  The fancy names are a nice complement to the small rooms.
