For me, it's all about 11 :)
Yup number 11 for me too. A much better contrast to the characters. Short vs tall, plain vs stripes, and red vs blue. I like the idea that the parents are at odds with each other. Much quikier.
The bed structure we discussed reminded me of this film made by Ernesta a few years ago. Go to 58 seconds to see it. It's a typewriter and more horror than you're looking for but the basic principles / construction is similar.https://www.youtube.com/watch?v=s_moLpTbgVw
