When you have kids, doing something unexpected can really get them excited. We saw this idea of installing a trap door leading to a small play area over at Nesting blog.

In addition to connecting a bedroom to a play area, this would be a great way to connect siblings' bedrooms. Sure, they can use the regular doorway, but this is a "secret" passageway!
