What do you mean by no breakfast, single breakfast and double breakfast in the hotel room type introduction? Thank you.

Excluding breakfast means that the hotel does not include breakfast, single breakfast means one breakfast, and double breakfast means two breakfasts.

Specific circumstances:

1. The breakfast provided by the hotel refers to the breakfast of the next day.

2. When you check in, ask whether breakfast is included in the room rate, including two breakfasts or one breakfast. If it's not early, use it in the hotel early and need to buy it separately.

If the room rate includes breakfast, you will usually be given a breakfast card when you check in. Just eat it with a breakfast card the next morning.
