Darken window with aluminum foil
Darken windows with aluminum foil on holiday:
Do you know that too: Holidays at last, but the little ones do not think about sleeping at nine o'clock because the hotel room is just too bright? My tip: Buy a roll of aluminum foil and Tesafilm in the next supermarket. So you can then tinker with your own blinds.
When sticking, make sure to attach it to the inner frame so that you can still open the window. The advantage: The room is not only perfectly darkened, it remains when daytime, the sun on it seems much cooler in the room ...
