For the Light-Sensitive Sleepers
By law, there are supposed to be smoke detectors in every room of a hotel. This is only true for hotels in Europe and the US, but you may find them in other countries, as well. However, how can you go to sleep with the smoke detector flashing its bright light into your eyes at night?
You can’t, which is why you should have some duct tape with you wherever you go. Take a bit of tape and cover the light, making sure not to cover any holes. And just like that, light-sensitive sleepers can get a good night’s rest.
