Then people would get to jump on giant beds, have to open big doors, and climb double sized staircases. And here and there would be double sized animatronic people who would taunt the guests about how small they were and what would become of them.

I thought about filling the rooms with helium to make everyone's voice higher, but this would involve lots of recycling, careful atmospheric control, and a nearly air-tight house. Might be too expensive.
