Can I use half a roll of toilet paper in the hotel?

Whether the hotel can use half a roll of toilet paper depends on the hotel's management regulations and your use needs.

On the one hand, if the hotel management regulations allow guests to bring unused sanitary articles, such as half a roll of toilet paper, you can take them away when you check out. However, if the hotel stipulates that guests are not allowed to bring hygiene products when checking out, you may need to abide by the regulations and leave this half roll of toilet paper.

On the other hand, from the point of view of use demand, if you think this half roll of toilet paper is enough to meet your needs and you have a suitable place to store it, you can take it away. However, if you think this half roll of toilet paper is not enough or inconvenient to use, you may need to buy suitable toilet paper according to your own needs.

In short, whether the hotel can take away half a roll of toilet paper depends on the specific situation. I suggest you know the hotel regulations and make a decision according to your own needs.
