We are going to attempt this, not for the same reasons as OP, but because our daughter is a bit of a terrible sleeper (she's two). If she sees us in the same room as her when she wakes up during any of her approximately 800 night wakings, it will all be over for everyone. So we are going to try to rig a curtain around her pack and play so she can't see us and has the illusion of being "alone" like she is at home. I plan to bring an extension cord and use a blow dryer to heat the stickers before I pull them off as that should help loosen the glue and ensure a clean removal. If not, of course we will pay for the repairs to the walls.
