Soundproof the room with a damp towel
It’s obvious that we won’t be the only guests in the hotel and that other people will also seek to rest and enjoy their vacations. For the sake of others, when wanting to enjoy watching a movie or listening to music at a high volume, we recommend this: Use a towel to soundproof the room.

Once again, moisten a towel, roll it up, and tuck it under the door pressing out. Doing so will prevent the sound from going out, and, additionally, the dust from outside won’t get in. Your neighbors will sleep peacefully, and your movie volume can be loud.
