Locking a sliding wardrobe door

I don't know if they still sell them, but have a look around at the local ironmongers or one of the sheds for a wardrobe sliding door lock and see what you come up with - you're looking for something like this

Deebrief used his keyboard to write :

Place a long strip of metal in the track. That blocks the door from sliding. That will not interfere with the other door. Remove the metal when you want the right door to slide.

If you want to prevent the guests from removing the metal strip, drill a hole in it and screw the metal downward through the bottom of the track.

The metal strip could be a trimmed bit of aluminum sold in the hardware store as flashing (a strip of metal used to overhang the eave of the roof so that no water can get under the shingles.)
